All these bounties have exposed a few bugs in oclvanityminer.  There were a handful of issues with the bounty list parser, and those have been fixed in git.  Another issue that also came up, the solve URL for vanity pool doesn't appear to accept POST requests.  It sends me back an error when I post something.  I changed oclvanityminer to use GET instead of POST for submitting solutions, and it seems to work.  I will post new binaries soon.

Edit: Pick up vanitygen 0.22
