Decoupled the function for getting the query of the badge filter

- Added updateBadge() which sets the title of the browser button to the
name of a selected badge query filter
- The badgeQuery() funtion now returns the full response - allows it to
be called from any part of the extension
- Added a new CRX Message which returns the result from badgeQuery()
- Name of badge query filter is saved for quick access

- Badge number now updates (to a blank string) when results are < 1
(before it wouldn't update at all)
- Non-final icons added
- Updated the version to reflect the previous changes
Query results shown in popup

- The results of the badge query is shown in the popup
- Added the "favorite filters" drop down within the popup; on selection:
updates the results table
- Clicking on an issue link of the popup triggers same action as quick
search (open tab)

- Added Handlebars templating (compiled)
- Upgraded to jQuery v1.9.1
- Moved to-do list to Trello
Updated README and description
