Consistent naming for Math_ functions (#542)

* Darkmeiro decompilation

Bg_Gnd_Darkmeiro decompiled, matched, and documented.

* give this a shot

* fix conflict

* one more try

* could be useful

* whoops

* ZAP2 stuff

* ZAP why

* ZAP again

* maths

* Factoriali -> Factorial

* soon, soon

* renames

* rand

* docs

* merged

* formatting

* little more cleanup

* asm crept back in

* changes to MathF

* smooth criminal

* functions.h
