Added multiplayer features to blackjack

[noittaM]

new commands:
tablenew: create a new multiplayer blackjack game.
tablejoin : join target's blackjack game.
tableleave: leave the current blackjack game.
tablebet: make a bet on the next blackjack round.
tablestart: start a blackjack match started with 'tablenew'.

the old '!blackjack' command's functionality has not been changed, you can't join a blackjack game made with 'blackjack'.

@noittaM - looks good at first glance, I'll need to do a more thorough review later on. Can you revert the changes to money.csv and bump everything in requirements.txt so that the out-of-date-dependency test passes?

I reverted money.csv and bumped everything to latest.
unrelated but the format of the frog API's payload seems to have changed and is causing issues, I'm not sure how you want it fixed exactly but doing something like this works.

if this is alright I can apply it and change the tests accordingly.
