-Fixed MapChooser translating the last map in a vote without extend to "Extend Map"

-Added convar sm_mapvote_novote to MapChooser. Default is 1. Set to 0 and MapChooser will not set the map when no one votes
-Added convar sm_mapvote_extend. Default is 1, set to 0 and Extend option will not appear, even if the other extend cvars would allow it.
-MapChooser now sets sm_nextmap to "Vote Pending" when the map starts. (Note: If using RandomCycle as well, it will be changed to RandomCycle's choice.)
-Nextmap changed to reset sm_nextmap if it is invalid at end of map intermission
