allow user to claim multiple winnings

[bthaile]

(contract call wired up in UI)

claimTradingProceeds on packages/augur-core/src/contracts/para/WethWrapperForAMMExchange.sol only takes in 1 market. Need it to take in multiple.

so that users can claim all ETH amm markets in one transaction

like convenience method on packages/augur-core/src/contracts/trading/AugurTrading.sol

    function claimMarketsProceeds(IMarket[] calldata _markets, address _shareHolder, bytes32 _fingerprint) external returns (bool) {
        for (uint256 i=0; i < _markets.length; i++) {
            uint256[] memory _outcomeFees = shareToken.claimTradingProceeds(_markets[i], _shareHolder, _fingerprint);
            IProfitLoss(registry['ProfitLoss']).recordClaim(_markets[i], _shareHolder, _outcomeFees);
        }
        return true;
    }

One method to claim all markets passed in would be preferral, but it'll be fine to have 2 convenience claim winnings methods one for ETH and one for USDT.

@bthaile Should be deployed. The remaining work is on the UI side.
