show balance of eth & corresponding tokens on foreign chain in info tab

The idea is that we have a quick point of reference to ensure that there is a 1 - 1 mapping, home -> foreign chains, for each token we have in the bridge.

For ex.

If the home contract has 100 eth...

ETH_TOKEN.totalSupply() + PAYMENTS = 100

where:

• ETH_TOKEN = the token on the foreign chain representing eth on the home chain
• PAYMENTS = sum of all authorizedPayments in the home contract where token == eth (0x0) & not paid or canceled.
