Fix icon loading for .desktop files (Bug 11078)

This code now checks multiple different ways that an icon can be
declared in a desktop file. It checks the absolute path, if it's
in the icon theme, if it's in the icon theme without an extension,
and finally if the icon is in the pixmaps folder.

Remove the drag highlight code (Bug 10450)

When dragging icons on the desktop there was a box showing which
cell the icon was going to be placed in. The issue is that the
bounding box doesn't always get cleared and ends up causing
different artifacts on different systems. For now, remove this
feature until it can be correctly implemented.
Updates for release.
Post release tag bump.
