Built-in ACS functions

These are all the functions that ACS has built-in. Note that these can only be used in scripts and not on linedefs or assigned to things. In those contexts, only Action Specials may be used, though action specials may also be used in scripts as if they were ACS functions.

When adding to or updating the definition of these functions, please update the Doom Builder ACS configuration as well. Thank you.
