`ethexe`: extend replySent to emit different event if value is claimed

[jekennedy]

Problem to Solve

In ethexe/contracts/src/Mirror.sol, the function replySent attempts to transfer tokens to a given destination, and then emits a Reply event. Depending on whether value is greater than 0, a transfer may or may not happen. It would be useful for the caller to know if a transfer actually took place or not.

Possible Solution

If value is greater than 0, emit a different event, like ReplyAndValueClaimed.
