Dealer Rewrite & Minor Fixes

• Dealer rewritten and somewhat more performant. More importantly it should be closer to the real deal..
• Items() class can now be iterated over to see all items that you have more than 0 of.
• charge_count is now optional and can be randomly generated similarly to the actual game
• When the shotgun is reloaded, it now follows the correct shotgun bullet distribution (Before, the amount of live shells was independent of the total shells; this is incorrect as the amount of live shells = total // 2)
• Meds will no longer allow you to surpass the usual charge count maximum.

v0.1.0

• Fixed the dealer, it doesn't completely fail to run now
• Proper abstract class for Engines
• Bugfixes to board
• BuckshotRoulette.make_move no longer returns the length of the shotgun unecessarily

v0.0.5

• Dealer didn't set self.me
• Board hash() function used old dictionary syntax for Items

v0.0.4

Initial Release! Mostly functional, I think!
