Run all replays in the /Tests/Replays directory

No more copying necessary. Makes it much easier to test new replays on
the fly through the unit testing.
Added 2.0.6 replay (which doesnt parse)
Added test replay for 2.0.7
Rewrote tests to be generic for all replays

Mostly changes the ReplayHas2Players method to check the number of
players against the TeamSize. renamed the test class to reflect this.
Added some helper methods to BitReader
Fixed ReplayInitData to work for 2.0.6 and 2.0.7

Unfortunately, "fixing" it means right now, parsing this file does
absolutely nothing in the end. GameType is missing, but we should be
able to use data here (swarm level, etc) if the player list is updated
to something more useful.
