Improved tab storage and tagging bug fixes

Change Log

Improvements

• Eliminate pre-emptive tab storage (#30)
  • Tabs would be marked as ready after being loaded. This had the potential to cause high memory consumption on a user with a great many tabs open. This is being switched to a less aggressive version where we only test readiness on a save request.

Fixes

• Fix/autocomplete trigger (#29)
  • Updating Enter check for highlightedIndex
  • Fix autocomplete now shows on first letter input
  • Updating tag storage to utilize existing tags
    • This add the existing tags to the stored_tags and removes the tags from the local storage. Basically just changing the key for stored tags.
  • Fixing close panel on double enter - Removed the delay in close on double enter.
  • Updating typeahead open trigger to include result check
• Fix/item tag association (#31)
  • Updating how the save data is being built - On certain sites the data returned from the server is not a complete set. This updates the object with cascading selection of data.
  • Update tag syncing
    1. Grabbing the current tab info prior to yielding the delay to avoid invalidating the tag save process
    2. Updating the API to send item_id as opposed to url
