Centralise engine access, add Portal FOV changer

- A bunch of stuff is now defined in one header, engineapi.h
- engineapi.c is responsible for setting up any interfaces/stuff that's
  used in more than one place
- mkgamedata is pretty much rewritten and now supports nested
  conditionals
- gamedata variables no longer have the gamedata_ prefix because it was
  just annoyingly long all the time
- vcall macros are somewhat revamped and support dynamic (gamedata)
  indices
- Portal 1 FOV can be set anywhere from 75-120 using fov_desired -
  tested in both the main versions currently used by runners
- A few typos were also fixed ("intput," "writeable," "indexes")
