Added functionality for OP_MAX action, Refactored Betting Ratios, and Removed Tie-Breaking

OP_MAX Functionality #71:

Added to player (action storage)
Added to real player (enabling real players to choose it) Added to monte_carlo (enabling monte carlo to choose it)
Added to round (enabling the functionality itself) Currently, if you have more chips than your opponent's remaining chips + the incoming bet, you get the OP_MAX option. If any bet option besides MIN_BET would over bet the opponent's max, it is removed as a choice. Also, if the opponent is all in, the player's options are limited to CALL, ALL_IN, and FOLD, since anything else would be redundant/pointless.

Betting Ratio functionality #77:

Reduced the low, mid, and high bet ratios down to a single class located in the player.py file named BetRatio.
Replaced every instance of the hard-coded values with a reference to the class, so that it can all be changed from one spot if necessary.

Tie-Breaker Removal #70:

Now when two players have hands that score the same, they split the pot. There is no tie-break round.
