[Gtkradiant] bug 664 - q3map2 in 1.2.11

[Timothee Besset]

bug 664 is about the stuff we are doing to provide q3map2 in 1.2.11
the main thing is to have updated version 4 quakev3.qe4 files for all games

I adapted skeleton q3map2 commands from what ydnar gave me, and verified
them on Q3 / RTCW / JKII. No updated setup at this point, there are still
a few things moving fast, but soon. If you have source access though, and
SoF2 / STVEF / JKII, please try to review the new skeletons and see if
they work fine.

1.2.11 release plans .. well I'd seriously like to have some release
candidates by the end of the week! (how many times have I said that..)
