sidebar patch

this is a first idea for use the sidebar.
I splitted It, because of the 1MB limit. (I changed something in Glade, so the diff is very big)

another try, beause its ugly to download the files.

regarding the huge diff and separate glade file...  I recently experienced this problem.  If you use the wrong version of Glade, it will rewrite the entire file and make your patch huge.  Stephane Delcroix answered my question about this in the following way:
-----
get the f-spot.glde file
open it in glade-2, do nothing, save.
svn diff f-spot.glade > glade.diff
open f-spot.glade in glade-2, do your modifications, save the file
patch -p0 -R < glade.diff
-----
Then create your diff the usual way.  It will only modify the part of the glade file that you edited.
