Proposal : What's Your Game? [Trivial]

I only noticed this when the new Wiki ruleset started highlighting it... Replace "GamePlayer" with "BoardPlayer", throughout the Ruleset, since both terms get used, and only one of them gets explained.

Also, replace all occurrences of "BoardPlayer", "GameBoard" and "CfJ" with appropriately escaped equivalents, to get rid of the needless (and unresolvable, since we can't create new Wiki pages) highlighting.
