Add a 'vcall mercylimit <X>' vote possibility
This could be used in teamgames, especially tdm and ctf. When a mercylimit/leadlimit is set, the game will endmatch after a certain lead of the stronger team.
E.g.: Team A leads 50 frags over Team B, mercylimit 50 is set. The server will now abort this match and end it. Same could go for ctf captures, e.g. 6-8 captures difference between teams.
