Show Profits and Losses on Equity Page

[luziusmeisser]

We should add two additional info boxes on the equity page, one for profits and one for losses.

These are just the cummulative amounts from these two events in Frankencoin.sol:

event Loss(address indexed reportingMinter, uint256 amount, uint256 reserve);
event Profit(address indexed reportingMinter, uint256 amount, uint256 reserve);
