Techwiki start

[Timo Kreuzer]

I have started a techwiki inside our wiki. It can be found at 
http://www.reactos.org/wiki/index.php/Techwiki/main
Currently only some stuff for win32k/gdi. Please add any info about nt 
functionality / links / tools you'd like to share there.
I still think it would be a good idea to move it into it's own wiki, so 
our wiki doesn't get even more messed up ;-)
