Changeset 5963 for code/trunk/cmake

Message:

Improved Visual Studio IntelliSense (tool that suggests function names etc.) performance by excluding all external libraries (headers used in our projects still get parsed) and the compilations (double work otherwise).
Curiously there is no official switch to disable IntelliSense. There's only a local and unofficial version that deals with removing a particular DLL.
However if Microsoft dares to create bugs, we dare to exploit them: Specifying "-Zm1000" instead of "/Zm1000" as compile flag messes with IntelliSense. It once took me half a day to figure that out since the causality between that and "IntelliSense is not working at all for any project" is rather unexpected ;)
