the game code asserts all the time, but seems to work when disabling
assertions..
so make sure assertions are really disabled with NDEBUG, even if _DEBUG
is set (like it is in debug builds).
this way I can at least get an unoptimized debug build that can actually
be tested.
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.
