More UI crap!

* Fix minor additional error in tab rankings.
* Remove FREE PLAY from intermission drawer, per Sal's request.
* Remove "second%s" from the end of the "Start in %d"/"Vote ends in %d" string.
* Rename cv_advancemap's "Off" value to "Same", to make the behaviour clearer.
* Make the "Start in %d" string now begin with cv_advancemap's string (ie, "Vote in %d", "Same in %d", "Random in %d, Next in %d"...
