[Gtkradiant] Mission statement - declaring current build official

[Willi Schinmeyer]

  Hi,

I've been using 1.6 for Jedi Academy since last September and it works 
just fine, once configured.

I've also made some changes (e.g. also connecting target2, target3, 
opentarget etc. to targetname and fixing transparency in models), sadly 
before the move to GitHub, maybe I'll create a proper GitHub fork and do 
some pull requests some day... (Until then it's available at 
http://sourceforge.net/p/gtkradiantfork/home/Home/ if you happen to be 
interested.)

So long,
Willi Schinmeyer
