Checking for unknown hashes opens a misleading popup message

[jrick]

A popup message at the bottom of the window says "Hash was successfully verified and the result was added to the verify log.", but "verified" here must mean that the input was decoded to a 32-byte hex string. This is a valid possible hash, but "successfully verified" makes it sound like it's an input previously submitted to the server.

Actually, that whole popup should probably go. It's not useful for known or unknown valid inputs, and invalid inputs show an error message in a more visible location.
