[Gtkradiant] spog branch

[Timothee Besset]

I exported the trunk and spog branch, started looking at the diffs. Since
the Alpha merge, and spog branch has not been synced with the trunk since
then .. I can't do much with it. Too many differences, either the Alpha
merge diffs or the actual spog diffs.

What I'm thinking about doing, is building diffs from spog and the trunk
before I started to merge Alpha in it. Then we can start thinking about
applying that on another temporary merge branch to keep a clear view of
the changes.
