Massive refactoring to support flavors properly.

Refactor the entire code to use TumblerFileInfo instead of separate
URI/MIME/flavor arrays. We now support flavors which means that
applications can request "normal" and "large" thumbnails and thus have
more control over what is created. This simplifies the code in a lot of
places. We now use a real GObject class called TumblerThumbnailFlavor
instead of a fixed-size enum. Cache backends can return as many flavors
as they want, each consisting of a name, a width and a height. As a
consequence, we can also get rid of the configure flags to
enable/disable normal, large and cropped thumbnails. The default cache
plugin shipped with Tumbler only supports "normal" (128x128px) and
"large" (256x256px).

Optimize the code a little bit. We now load the TunarFileInfo and
ThunarThumbnail only *once* for each URI instead of loading them once in
the scheduler and again in thumbnailer plugins.

This needs careful testing. I might have introduced a few memory leaks
here and there, plus new bugs... you never know.
