merge bday/xmas w/ main

ok. this should avoid calling switch inappropriately. also, add skip to trophyrace and add the per-team achievement reporting.

so, lack of this was causing the team area to be too squat. at this point tho, I get the impression qt.css is outright replaced by birthday/christmas. This seems inconvenient, and if so, we should merge in changes to qt.css which has quite a bit more stuff in it
