[kdev3.5] doxygen part exit

[Bernd Buschinski]

Kdevelop3.5-svn exit (not crash)
when I import
https://zerowing.idsoftware.com/svn/radiant/GtkRadiant/branches/ZeroRadiant
not the svnpart, the doxygen part with 
Error: @INCLUDE = DoxyConfig: not found!
in the console.
This error is not fatal and no reason to exit kdevelop.
The patch should fix it, I just uncomment the exit(1), the rest are just 
unnused variables.
