Use whatever names you want for your music. So long as you prefix the lumps with O_ or D_, it doesn't matter anymore.
DISCLAIMER: Linedef type 413 (change music) and Lua scripting is not tested.

Angles now go from 0 to 0xFFFF (360 degrees == FRACUNIT) instead
of using a full UINT32. Lua only has one number type, so signedness
gets in the way of using angle_t directly. This handling of angles
matches up with how ZDoom ACS scripting and the like does it.
I also changed all the integer casts and pushes of fixed_t to
their own macro in preperation for possible future seperation.
EvalMath is for SOC only.
It spawns an entirely seperate instance of Lua and requires
uppercase-only strings, and it's ability to parse strings to
enums is redundant to Lua's _G table (try using
_G["MT_BLUECRAWLA"] for instance)
