Bring sanity to the header files. Most .h files were not used to declare the externally visible variables and functions of the .cpp files, but only to #include things and declare things that were needed by that .cpp file itself. This resulted in a lot of duplication. Now the .h files only declare what is externally visible from the corresponding .cpp files. Starfighter.h includes all the other .h files, and all .cpp files only #include "Starfighter.h". Functions and variables that were not used outside the .cpp file that contained them were marked static. Variables defined in .h files were moved to the appropriate .cpp files.

Flatten objects which only contain static functions. There is no reason to have objects which contain only static functions and no variables. These functions have been moved to the global namespace and are now defined in .cpp files. The math functions are very small and have been put in math.h and made static inline.
