When contract receives ETH from someone else than contract owner, it should transfer equivalent amount of tokens to the sender of funds.

This requires adding constructor parameter and function to set the conversion rate (limit to owner only), initially it should be about 200000000000 wei = 1 wTLO (100 atomic units), or rate 2000000000:1 measured in atomic units, capped to absolute maximum of 1 million wTLO per transaction to avoid draining token supply for conversion from TLO to wTLO.

Converting tokens by request back to ETH doesn't seem very good idea as the contract needs some ETH reserve for bridge to work.
