v0.994 Final preview

Full Changelog: v0.993-beta...v.0994-beta

A first really public release for people to test

This changes the User Interface for clarity, adds PIN folders and the ability to look for PINs by type. I will continue to work on at least one foreign language version (German) and to do further testing. Please raise issues on the github tracker.
