Yet another attempt at a clean commit history for the Songkick Spice plugin.
If the query is just concert or concerts, use the user's current location.
Check relevancy of artist and location with DDG.isRelevant to make avoid spurious matches.
Don't convert Array -> jQuery objet -> Array unnecessarily.
Fix for checking isRelevant against an empty query when we use the location API to determine the user's city.
Make twenty_four_to_twelve_hour_time a local function.
Moved to 2-line layout for upcoming events. Now constructing the event title string manually for better display.
Be even more careful when handing API responses from Songkick.
Scope Songkick event CSS.
Require a preposition for Songkick concerts queries.
Changed similar artists Spice to trigger on (artist|band|musician)s (like|similar to) foo.
Be more specific about Songkick Spice triggers--require (around|in|near) for queries longer than concerts?.
Added tests for queries that do not trigger the Songkick spice.
Remove "the area" from location queries.
Passed metroArea.displayName through from location query to event query.
