In the main-tab, when changing tag, buddy or divemaster,
update the corresponding completion model.
This is a quick-fix and the wrong thing to do. It works only
if the currently shown dive is changed, which is not a given.

The DPI value in the print_options structure was never initialized.
This could lead to random DPI values and crashes. How this ever
worked is a mystery.
Therefore, read and write the DPI value from the settings just
as the other print-options. And initialize the corresponding dialog
widget to this value.

It is completely incomprehensible why these fail. And why randomly restarting
sometimes fixes them, and often doesn't. At this point there is no incremental
value in having this test. If it were to ever catch a real bug, we wouldn't
realize it because we are too well trained to ignore the problem.
Very disappointing, but IMHO the right thing to do.

Thanks to commit 299ba20364 ("Update translation source strings") all
the translated terms in the Command classes are now part of the base
class. So remove the references to the subclasses in the translation
sources as well.

We need to always call the tr() function of the base class. This will have

Qt's memory management scheme is completely broken and messes
with common expectations.
QObjects are organized as a tree. The children are destroyed
in the destructor of QObject. This means that they are destructed
after the destructor of the parent object has run and its
sub-object were destructed. Obviously, this makes no sense as
the child objects should be able to access their parent at
any time.
To restore the commonly expected deterministic order of
construction and destruction, one might simply do away with
Qt's silly object tree and organise things using classical
subobjects. However, that breaks with the Qt-generated UI
classes: The objects generated by these classes are *not*
destructed with the UI class. Instead, they are attached
to the widget's QObject tree. Thus these are again destructed
*after* the widget! Who comes up with such a scheme?
In our case this means that we cannot have models used for
TableViews as subobjects, because the TableView needs the
model to save the column widths in the destructor. Which,
as detailed above is called *after* the desctructor of the
widget! Thus, turn these models into heap-allocated objects
and add them to the QObject tree.
Funilly, this exposes another insanity of Qt's QObject tree:
Children are destructed in order of construction! One would
expect that if objects are constructed in the sequence
A, B, C one can expect that C can, at any time, access B and A.
Not so in Qt: The destruction order is likewise A, B, C!
Thus, take care to init the widgets before the model. Jeez.
Finally, print a warning in the column-saving code of
TableWidget, so that these kind of subtleties are caught
in the future.

The custom TableView widget saves the table width on destruction.
For that, it uses the "objectName()". Since the table of the
DiveComputerTab was simply called "table" in the UI file, the
widths were saved in that generic section. To avoid future
name-conflicts, rename the widget to "devices".

This was just ugly: the column with the "trash" symbol and the
name had the same size. On creation of the object, make the last
column expand and adapt the size of the "trash" column according
to its content.

Recently the QStrings were replaced by std::strings in device.cpp
so that they can be accessed from C-code. However, libstd being
modelled after C, constructing a std::string from a NULL pointer
leads to a crash.
Fix one case where this was overlooked.
Moreover, replace a null-pointer check by empty_string(), to
treat NULL and "" equally.

Because of subsequent changes there is no clean way to just revert the changes
introduced in commit 8b36cf1051 ("desktop: offer different colors for info tab

This also restores a tooltip value that was inadvertantly removed in that

The preference setting seemed far too strange to do this. And not very user

text and background colors in the palette, and make sure we get notified if
that changes.

Add a preference option to set the color of the text on the information tab to
either MediumBlue, LightBlue or Black. The last two of these colors are meant
to enable areadable font contrast on displays with dark mode.
The choice is saved with the other preferences.
[Dirk Hohndel: this isn't really about dark mode, so changed many of the types
and variable names, changed the user visible texts, and
addressed some whitespace issues]

It appears that Xcode 12 applies some rather self defeating logic when picking
build architectures in release builds for the simulator. It adds aarch64 by
default and I can't find a way to turn that off from the command line. At the
same time, you can't link against the simulator if you have build with aarch64
as the aarch64 simulator doesn't exist, yet.
Since I couldn't get any of the claimed workarounds to work, I'm forcing Xcode
11 to be used in the Action.

When encountering a <weight> tag, we would parse into the last
weightsystem. However, we only create weightsystems when
encountering <weightsystem> tag. Therefore, this code would
either crash or overwrite the previous weightsystem.
Instead, create a new weightsystem for each <weight> tag.
Moreover, make sure that inside a <weightsystem> tag a
weightsystem actually exists. This should be the case,
but who knows...?

This should allow us to then do both 32 and 64 bit Windows builds in our CI/CD
and of course for our releases.
In order to still be able to use this container in a GitHub action, aggressively
remove things that we won't need during the build. Since we use the experimental
-squash argument during docker build, this should get us a much smaller container
image in the end.

We previously tried to build the MXE Docker container on GitHub using
an Action, but that really didn't work well and was a lot more trouble
than it was worth.
So this goes back to an offline build mechanism where I simply create
an updated Docker image when needed and push that to Docker Hub.
But this nearly hides the most interesting change here - we are finally
switching to using 64bit binaries on Windows. It's 2020 and fewer than
1% of our users use 32bit Windows machines. We'll need to expand this
to be able to have both a 32bit and a 64bit version of Subsurface for
Windows. But for now, this solves the problem for 99% of our users.
