[Gtkradiant] 1.2.11 RC1

[Timothee Besset]

Current RC1 builds are up:

http://zerowing.idsoftware.com/nightly/linux-radiant-1.2.11-rc1.x86.run

The updates to ChangeLog links and credits are still up in the air. I
didn't get any feedback about the q3map2 integration and the new qe4
templates, so I'll just assume they are working fine. If no blocker comes
up, I think we are looking at a release tomorrow.
