[Gtkradiant] Alpha merged into Trunk - done

[Timothee Besset]

I have copied the TmpMerge-1_1_1 back into the trunk. All the relevant
changes on Alpha branch since last time we had a sync are now applied in
the trunk.

It is probably time to start working on a roadmap for 1.2

First thing will probably be to look at Spog's changes and merge some of
them in the trunk.

As of now, you can rebuild the trunk and send in patches to fix crashes
and all sorts of side issues that might appear post-merge.
