Clean up gameinfo_init() and other random stuff

- Just ask the engine for the game directory instead of doing the stupid
  argv sniffing hacks from the early days of trying to get the damn
  thing working.

- Also add some other path variables, functions and whatnot, and do some
  other minor tidying up.

- Also also, another damn copyright year, somebody please help me.

Unfortunate negative effect off this change: con_init() no longer
reports the game name, because it has to happen before gameinfo_init().
I've decided I don't really care, though.
