sometimes bad signature in REVEAL_SIGNATURE

[hannesm]

and I've been through this in my OTR implementation... the trick is to strip leading zeros from the DH (a similar problem occured in http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8014618, and it is not clear which JDK versions (if any) have actually fixed the issue). from the OTR protocol definition, it says that no DH public should be zero-padded on the wire...

would be great if you could look into this and maybe find a fix!? thanks!
