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.

This isn't a bad idea, but I think I want to hold off on it for now unless someone else wants to do it. Discord's API is getting an upgrade for bots soon that has more tailored UI functionality rather than embeds + emojis. We could make something that looks like this in the future. I'd have to rewrite a lot of the code for this anyways and would rather spend my time making sure the core features are working.
