Unexpected Paste of Hex Results in Nothing

[shannona]

Pasting hex bytes using the "+" that aren't in the expected format results in no paste and no error.

Example:
59 F2 29 3A 5B CE 7D 4D E5 9E 71 B4 20 7A C5 D2

I'd suggest stripping out characters that aren't [0-9A-F] and/or reporting an error.

I had a new problem, #209, show up while I was testing this.

But, pasting hex bytes in with the division space seems to work fine, so I'm going to assume they're not related and close this out.
