Additional bug fixes

This adds a fix for the editor so that if a student is using TinyMCE they do not see an error. Some other caching was also included.

Enhanced editing

When using the tiny_stash editor and saving an item with a drop, or a trade, instead of a short code appearing in the tinyMCE editor, an actual visual representation of the element will be shown instead.

Privacy provider

This add the privacy provider which was missing from the initial release.

This plugin does not store any user data and so has implemented the null provider.

First tiny stash

The first version of tiny stash. This allows you to create items and trades and then directly insert them through the Tiny MCE editor into your activities in a course.
