Reset the icon_view style on style change (Bug 10605)

Since xfdesktop now properly responds to xfsettingsd changes we
need to handle the race condition at launch. This patch changes
it so that the style change for the icon view happens in a low
priority callback. This ensures that the style gets reset only
once if there's a batch of changes to process and will happen
after xfdesktop has loaded. This is different from the previous
callback patch in that the entire icon view doesn't get recreated.
G_CONST_RETURN has been deprecated
Use GIO directly for delete/trash operations (Bug 10778)

Instead of passing the list of files over to Thunar via D-Bus to
trash or delete files, just use the async GIO functions directly.
We'll continue to use Thunar for the other operations because of
the file transfer dialog.
Filter out changed events for special icons (Bug 10755)

Special file icons are the trash, home, and filesystem icons. The
only events that would require a refesh would be an add/delete
event for the trash can. This patch filters out all the change,
attribute change, and changes done hints to prevent the icons
from being reloaded due to those events.
Updates for release.
Post release tag bump.
