* Major improvements to fife_math.h and added corresponding Python bindings. Users now have access to FIFE's internal math functions. These functions are recommended to be used by all clients if required. Note: this may cause some problems with certain compilers. I hope this wont have to be reverted. TODO: remove the static constant globals somehow. * Adopted the new math functions for all subsystems * Improvements to DeviceCaps. It now detects all possible screen modes. * User can now select 0 for their bpp and it will attempt to initialize SDL with the current screen bpp.
