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*

way, that it cannot move through walls of the world, is influenced by gravity and
acceleration. This animator is useful for example for first person shooter
games. Attach it for example to a first person shooter camera, and the camera will
behave as the player control in a first person shooter game: The camera stops and
slides at walls, walks up stairs, falls down if there is no floor under it, and so on.
