running-from-dist changes and a working Dist::Zilla config

Added the FindBin + use lib trick so that you don't have to do perl -Ilib to run the scripts from the dist dir (assuming the dependencies are installed).

I also wrote a dist.ini file that is used by Dist::Zilla to generate a cpan distribution. Dist::Zilla (dzil) is really cool and http://dzil.org/ has all the info, but for just using it this should be sufficient:

    cpanm Dist::Zilla
    dzil authordeps | cpanm
    dzil build
