Add a Tagging module.

Browse Source 
* It uses an indexedb datastore.
* Fix the api of the indexeddb wrapper now that I have some real world usage
  examples.
* Implemented API Calls:
   * UpdateTags
   * GetTags
* Exposed but unimplemented API Calls:
   * GetVersesForTag
   * Sync
* Add a tooltip that shows the tags for a reference to the reference link.
