changes on updateResults, populate by @cervengoc on #781

Use <strike>string concatenation</strike> Bulk DOM insertion instead of DOM manipulation at populate. 

Tested with several BIG lists and the "data" configuration ( not using query )
This does give me about a 45% speed boost as measured with chrome v35. 

Tested also on iexplore ( but no measured, still feels lighter )
