Add 'httparty' as a dependency in the gemspec.

The 'httparty' gem is required by this library but not in the gemspec. Fixed
this by adding an explicit dependency for the current version. If prior
versions will also work, this version number requirement can be relaxed.

Bumped the version number to force rebuilding of the gem.
