Create a new class, which performs all thumbnailing code.
This is mostly code reshuffling. Thumbnails are extracted
either from a cache or thumbnail calculation is started in
a worker thread.
Since getHashedImage() is called from a worker thread it
makes no sense to call subfunctions in yet another worker
thread. Remove these calls.
In contrast to the previous code, on error the background
thread produces a failure image, but it is not yet shown.

In imagedownloader.cpp the only thing we need from the picture struct
is the filename. Therefore, use QStrings instead of the picture struct.
This simplifies memory management.
Remove the clone_picture() function, which is not needed anymore.

SHashedImage was a subclass of QImage, which fetched the image according
to the filename hashes. Turn this into a function, as this is much more
idiomatic and flexible.

Remove a semicolon after Q_OBJECT and a few others after the closing
braces of while loops.

If loading from hash failed in the saveImage() slot(!) it would
recurse into loadFromUrl(), which would generate a new network
reply. Very scary and a (small) wonder that it worked.
Let's try to make this all more explicit.

The QNetworkAccessManager is only used in the load() function. No
point in it being a subobject.

In core/imagedownloader.cpp the helpers cloudImageUrl() and loadPicture()
are made of static linkage.
The global variables queuedPictures and pictureQueueMutex were moved
into the loadPicture() function, because they are used only there.

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
