Add a way to fast-forward game time
This will be mostly useful for skipping cutscenes in Left 4 Dead games. It may work in other games, but probably won't really be as useful. Committer's note: this was adapted a fair bit from woz's original code, hence the joint copyright, but he did most the hard work of figuring out how to get this deep into the engine's call stack. Thanks! bill also provided a fair bit of help figuring out missing gamedata and fixing compatibility with L4D2 2147 and later. Also thanks!
