On deletion of a single or multiple pictures, the whole DivePictureModel
was repopulated, which was clearly visible in the UI, owing to the
reconstructing of all images in the profile plot.
To avoid this vexing behavior, implement proper deletion routines in
DivePictureModel and ProfileWidget2. Since this needs sensible erase()
semantics the QList<PictureEntry> member of DivePictureModel was
replaced by a QVector. A QVector should be the default anyway, unless
there are very specific reasons to use a QList (which actually is
a deque, not a classical linked list).

The function removePicture() had a flag "last", which would indicate
that the called had finished removing pictures. Only then would
the model be recalculated.
This is a strange interface and, matter of fact, the caller was buggy:
if the last picture to be removed didn't have a proper url, removePicture()
was never called with "last" being set.
Change the interface to take a list of pictures to be deleted. This
will allow us to make picture deletion smarter in follow-up commits.

In the old code, we used to reload the whole picture list on drag & drop
to the profile. Instead, only update the drag&dropped picture and repaint
the profile-pictures.

The size of the to-be-created thumbnails was passed from DivePictureModel
to Thumbnailer. This became more and more bothersome, because the size
had to be stored with the request. Calling from Thumbnailer into
DivePictureModel was not an option, since this is not linked to all tests.
Therefore, move these functions to the Thumbnailer class.
Since the maximum thumbnail size is now known to the thumbnailer, the
dummy and failure images can be precalculated, which makes switching
between dives faster.

Connect the thumbnailer signal to the dive picture model slot.
This needs some code-reshuffling in the dive picture model.

To potentially conserve memory, don't keep copies of scaled thumbnails.
Scale the thumbnails on demand.

This implements different zoom levels for the dive photos tab as
suggested by Stefan Fuchs <sfuchs@gmx.de> in #898.
The zoom level can be changed using a slider or CTRL+mousewheel.
Zoom levels range from a third of the standard thumbnail size to
thrice the standard thumbnail size.
Thumbnails are cached in maximum resolution and scaled down on
the fly. Because the profile widget took its pictures from the
photo list model, an extra picture copy with a fixed size had
to be introduced.
The UI is still a bit crude.

The constructor and the list of pictures was protected, but the
class neither had friends nor subclasses (a subclass was removed
in a recent commit).

In the dive picture tab show pictures of all selected dive.
But at the same moment take care that in the profile only
pictures from displayed_dive are displayed.

The removed comment in qt-models/divepicturemodel.h described

The code of DivePictureModel used a QHash to keep track of thumbnails.
Not only was the code rather complex - it also had the consequence that
pictures are sorted according to the hash function, i.e. seemingly
random.
This commit replaces the QHash by a simple QList which keeps track
of thumbnails and some meta-data.

Note that constructs like QList<QFuture<void>> is incompatible with
pre-C++11 compilers. But the code base is so full of C++11isms that
we may just as well remove asymmetric eye-sores of the kind
"QList<QFuture<void> >".

This required a bit more untangling, but with this it seems we can build
subsurface-mobile again (at least on the desktop).
Interesting is the removal from inside the ImageDownloader of the call to
DivePictureModel::instance()->updateDivePictures() - which actually could
cause some interesting recursion issues. If it turns out we did indeed
need this, it needs to be re-architected.
