[Gtkradiant] new 1.2 nightly

[Timothee Besset]

New 1.2.1-nightly is available.
http://zerowing.idsoftware.com/nightly/GtkRadiantSetup-1.2.1-nightly-01132002.exe

It's not publicly/officially available on the nightly page yet, but it will 
be soon. Most noticeable changes since last setup:

- spog's map-module branch merged in, fixes various bugs and misfeatures
- BSP monitoring / project template works again with long pathnames / 
spaces in install (went back to short win32 path names)
- Wolfen's Q3Rad manual updates
- ydnar's q3map 1.2.1-y8 with lightgrid common shader and editor image
