FPOINT -> Math::Point & other math functions

- changed FPOINT to Math::Point and some functions
  from math module to the new implementation
- moved old function and FPOINT struct declarations to math3d.cpp
- removed some unused functions in math module
- fixed some #include dependencies
- moved #define STRICT and #define D3D_OVERLOADS to compile options
