Bump version

Overview of changes:

 *  Enabled rpmstuff and debstuff specific tokens

    These can be used to (somewhat hackishly) try to mitigate
    differenceds between distros.

 *  Fixed printing error message to stdout
 *  Fixed broken error message

 *  Big code cleanup

    Only refactoring, but we needed to get up to date with style.
