Sort & Filter functionality

 - [x] Ability to sort individual columns
 - [x] Ability to filter rows from quick header cell
 - [x] Standalone folder for addons as well as automated gulp task 
Mostly thinking that on a large grid (100,000+ rows) if I want to type a filter of “DoubleClick” then I don’t want it to kick in a js array search 11 times (no matter how blazing v8 / our algo is!)

Usual approach (that I know of) for this is to queue up the search and cancel it (ie steTimeout / clearTimeout) so it does the search a fraction (100ms?) after each character
