Split out the actual filtering from the MultiFilterSortModel.
Create a DiveFilter class that does the actual filtering.
Currently, mobile and desktop have their own version of this
class, though ultimately we may want to merge them.
The idea here is that the trip-model and undo-commands have
direct access to the filter-function and thus can take care
of keeping track of the number of shown dives, etc.

In the future we might want to use undo-commands for mobile as
well (even if not implementing undo).
Therefore, move the undo-command source from desktop-widgets
to their own commands top-level folder.

In TabDiveSite::selectedDiveSites(), the QItemSelectionModel::
selectedIndexes() function was used. Thus for every selected
dive site 8 entries were added to the return-vector!
Instead, use the QItemSelectionModel::selectedRows() function.

This one-liner was called in only one place from the same class.
Just fold it into the caller.

The dive-site-edit and dive-site-table tabs both put the filter
into a special dive-site mode. When switching between both, it
could happen that the one got its show befor the other got
its hide event.
Thus, the first would start dive-site filtering and the second
stop it. Now the app was not in filter mode even though it should.
To solve this problem, add reference counting for the filter's
dive-site mode. In both tabs call the enter/exit functions
on show/hide. In the dive-site-table tab, when the selection
changes, use a set function that doesn't modify the reference count.

This feels more natural than selecting a single cell. Still,
the "delete" cell is not visibly selected, which give a
strange impression.

When in dive site tab and some dive sites are selected, show only
dives at those sites. Simply read the selection and pass it to the
filter.
Start and stop filtering when switching to and from the tab,
respectively.

Add a "purge unused dive sites" button to the dive site list.
Connect it to a new PurgeUnusedDiveSites command. Implementation
was trivial: simply copy the DeleteDiveSites command.

Stretch the name and description columns in the dive site table,
so that they don't start too small. This should only be a temporary
solution, as it disables the save column width to preferences
feature of TableView.

Simply copy the code of note editing. It's a bit more complex,
since we have to parse the Gps coordinates. For consitency,
rename the COORD field to LOCATION (the field in the dive_site
struct is called LOCATION).

If the name of a dive site is edited, it might wander somewhere
else in the table and thus out of view. Hook into the "dive site
changed" signal and scroll there.
The code is rather subtle as it depends on signals being called
in a certain order: First the item is moved in the model, only
then can we scroll to the correct place.

When adding a dive site, enter the name field of the new dive site.
Thus, when adding a new dive site, the user can immediately edit the
name.
The code is rather subtle: It hooks into the dive site added signal
before executing the command and unhooks afterwards. This only works,
because signals are executed in order of connect - thus the model
adds the index first and only *then* is the field edited.

Implement a dive site addition undo command and connect it to
the add dive site button. The added dive site has a default
name ("new dive site").

The LocationInformationModel used to sort its entries and was completely
rebuilt after every change. This makes it rather complex to support
incremental changes.
Instead, keep LocationInformationModel sorted by UUID so that indexes
are consistent with indices in the core dive site table.
Implement sorting by other columns than name and enable sorting in the
dive site view.
Finally, don't cache the list of dive site names for the mobile app,
since that would also need some rather convoluted methods of keeping
the list up to date. Calculate it on the fly.

Add a very simple tab-widget presenting the list of known dive sites.
The table is rendered using our custom "TableView".
The (mis)uses the "LocationInformationModel". It moves the items
to be displayed (delete, name, description, number of dives) to the
front and makes the others hidden.
Moreover, it was necessary to limit the geo-tag decoration role to
the name to avoid having the icon next to each column.
Make the trash-can icon active and the name and description editable.
This is modelled after the cylinders-table code.
