Verify does not print signature when verify fails

[basxto]

Verify does not print signature when verify fails, instead it writes [!] Verify failed into the file.

build/bin/mpqcli verify -p ../Demo01.w3m > signature1

Thanks for reporting this. I just merged a PR and a new release which solves this. See #132. Please reopen this issue if the problem remains.
