dhewg afebd7e1e5 Untangle the epic precompiled.h mess
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.

Parametric physics
Used for predefined or scripted motion. The motion of an object is completely
parametrized. By adjusting the parameters an object is forced to follow a
predefined path. The parametric physics is typically used for doors, bridges,
rotating fans etc.
