v1.30 - Devel::Loaded, pmeth, and basepods fixes as well as moving to a GitHub repo

  - Fixed Devel::Loaded to not include itself in the output
    (thanks to NEILB@cpan.org for spotting this problem). As long
    as you don't have files like 'MyOwnDevel/Loaded.pm', you are
    good to go.
  - Patched pmeth to flag constants (thanks to jpierce@cpan.org).
    Note that XS constants are not yet flagged (needs some C-fu
    applied).
  - Patched for basepods now in 'pods' in modern Perls. I guess
    the patch was from a Perlgnome, as there was no Requestor :(.
  - Moved to Git for source control.
  - Added GitHub repo at https://github.com/markleightonfisher/pmtools.
