Mission email gives a slightly incorrect password to the rover

The login nari02 is correct, and the password mendanciouspolyglottal should be mendaciouspolyglottal, without second n — or maybe there should be some hint about fixing the typo

Nice catch; thanks.

mentioned in issue #164

Kind of embarrassing that this shipped in the beta release. =( Oh well. Maybe that means we should cut a beta-4 sooner rather than later.

changed milestone to %beta-4
