Proposed version 0.05

* This incorporates version 0.04 from CPAN, but that version failed some unit tests with newer perls.
  Thus, this is version 0.05.
* Fix a major bug that made tests fail. I don't know if or how this ever worked before with newer perls.
  (see $self->{json}->canonical() call in lib/Template/Swig.pm)
* Sync up with version 0.04 from CPAN
* Update docs
* Fix test warnings
* Don't run pod-coverage.t unless RELEASE_TESTING
* Whitespace consistency changes
* Removed placeholder ignore.txt
