cutealien 3d2a55e788 Replace header guards in source folder to avoid using identifiers reserved by c++
Basically fixing original Bug#427 reported by MArkus Elfring.
Unfortunately there are still more defines (in IrrCompileConfig.h) which also are not nice c++
Lots of files touched for very minor cleanup *sigh*
