Prevent requests to non-payable contracts

[AlmostEfficient]

Area/Action Requesting funds with the /faucet command to a contract that is not payable

Expected behaviour Don't create a transaction, scream at requester (optional)

Actual behaviour Funding request made, bot crashes after as the tx fails.

Description Need to add a check to identify if the submitted address is a contract. If it is, check that it's payable, and only then create a transaction. Notify the requestor that a funding request was not made if it isn't payable.

Not doing this, waste of time.
