Album art support. Based on FS#3045, but heavily modified to adapt to MoB and for cleanness.

The cover pictures are loaded from external bitmaps. JPEG and embedded art are not supported. The pictures will only be drawn on the main display. There is no resizing but it is possible to specify the WPS bitmap size in the bitmap names (e.g. cover.100x100.bmp).
The bitmaps are stored in the main buffer and read directly from there. Currently, duplicate bitmaps will simply be present several times in the buffer, but this will be improved.
To enable for a target, #define HAVE_ALBUMART in its config file.
