In Send pane: don't proceed if token amount is 0

[tab00]

Currently it's possible to send 0 tokens, and the transaction gets processed on the blockchain. It normally wouldn't make sense to do that and would be a waste of gas fee.

So maybe there should be a validation error message if "Next" button is pressed when amount field is 0 or blank.

Ok, it's a valid operation, but like you say why would you? unless you're a developer testing something .
