Reimplementation / Improving of map-vote

[RedstoneFuture]

1. Reworking game start process for map vote, Reworking map vote

There were a few places in the game startup process that needed fine-tuning, because in case of a Map Vote we habe a phase between the "start of the lobby" and the "initialization of the arena", which needs to be considered.

2. Adding player permission check for "mw.vote"

3. Adding tab completion for vote command.

4. Update of the /mw start command
