Make captain's pick optional by vote

[39ma]

Bot already have balance team sort function, but players have optional function to make manual picks. Its good, but it would be better if manual pick will be activated by voting, not by 1 player.

For example, now its if someone writes q!tdraft a pick menu immediately appears.

Suggestion is someone from players write in chat q!tdraft, then a voting for to enable manual pick will popup. If n% of players clicked "yes", the manual pick will start.
