Integrate AMM / CLOB into core code

[metaproph3t]

Once the AMM / CLOB is found / completed, we need to integrate it into the code.

Specifically, the code should display the following behavior:

• For each member, member_expected_value := (conditional-on-pass price - conditional-on-fail price) / total supply
• net_expected_value := member_1_expected_value + member_2_expected_value + ... member_n_expected_value
• When net_expected_value > 0, allow users to pass proposals
• When net_expected_value < 0, allow users to fail proposals
• When a proposal is passed, allow users to redeem conditional-on-pass tokens and conditional-on-fail deposit slips for real tokens
• When a proposal is failed, allow users to redeem conditional-on-fail tokens and conditional-on-pass deposit slips for real tokens
