RLGWebD: rlgwebd.js annotate

annotate rlgwebd.js @ 40:f7116eb3f791

rlgwebd.js: refactor some game-starting code. Separate things like checking for games in progress, starting a new game, and figuring out where the lockfile and ttyrec should go. This allows e.g. the games-in-progress check to be used to create status messages. It also keeps the argument list for the TermSession constructor to a sensible size.
