[Gtkradiant] new stuff in CVS

[Timothee Besset]

There is a bunch of new things in the CVS. From the CHANGES file:

02/05/2001
   TTimo
   - added makeversion.sh to the root, will generate version and date files 
before compilation
   version.h and date.h
   - cleanup and fixes to the linux setup scripts

   Spog (CVS add and config by TTimo)
   - win32 setup script, run setup/setup.sh from cygwin to create a working 
directory for the setup <STILL EXPERIMENTAL>

I don't have a lot of time to expand on the changes, but basically Radiant 
relies on version.h and date.h to build the About dialog. Those are 
generated from a shell script, makeversion.sh. cygwin is now REQUIRED to 
compiled GtkRadiant. The call to makeversion.sh is included in the MSVC 
project. Let me know if you have trouble making this work. You can also run 
manually makeversion.sh from the bash shell to generate the files.

Otherwise, I commited Spog's new setup script. This stuff is not very CVS 
firendly, so what you need to do is CD to the setup dir and execute 
setup.sh .. it will copy GtkRadiant directory into SetupWorkDir and 
configure for setup building (IS is required).

Feedback is VERY welcome
