6 update3 - Profile selection bug fix & a few other things

Correctly(hopefully) fixed getAutoProfileIdForUrl() function to correctly match profile siteList URLs in all cases which @Jither mentioned.
Changed content.js to use querySelectorAll instead of using and including all of jQuery.
Reduced permissions from "tabs" to "activeTab" greatly increasing our security and surface area of exposure.
Removed the need for the sourcemap since it had no point or usage for us since January 24, 2014 mentioned in http://blog.jquery.com/2014/01/24/jquery-1-11-and-2-1-released/
A bit more cleanup/maintenance.
