Removed the "validate" button.
Voting for a map is now considered as validating. No need for a button anymore.
Fixed runtime error :
When using matchmaking, if the vote map was activated, some variables concerning the landmarks were initialized before the vote. So if there was a map change because of the vote, the variables were intialized with the landmarks of the previous map.
