• include reviews with AppDetails
• add method dump_raw to make debugging (and field discovery) easier
• featureGraphic now evaluated reliably
• AppDetails now also include developerEmail and developerWebsite
• AppDetails retrieval is now faster (as a "fallback loop" could be removed)
• several fixes and adjustments

• add parsePrivacy() method to retrieve privacy policy
• rework parseCategories() which was broken due to site changes. It's now using local definitions and now returns an array of objects instead just category IDs
• fill in missing details in parseApplication from embedded protobuf and JSON, also adding contentRating this way
• some more minor fixes and adjustments

This is a maintenance release, adjusting the class to the latest Playstore redesign which broke most methods (see #20).

The original version written by me was improved by another friend named Izzy.
Finally, this version is ready to use.
