Fix gather integration

Fix gather integration.

Tricky thing will be recognising the proper state.

• Ping website every 3 mins or so for gather state. When gather picking is done on the webpage, change map.
• Change maps automatically, but not if there's a game running.
• If its combat or there's classic game runnig with less than 8 players, assume the server is free.
• Print players and teams for the next gather.
• After every won round, update the round information straight to ENSL web.
• Mapvote after 2 maps should start automatically but keep it as a separate plugin feature. When 2 maps are played, disable automatic mapvoting temporarily.
• Allow joining next gather via command and add optional argument for map votes.
• Allow fetching of gather status via command.
