Added a generic Brix test page for 1 div

Added a generic Brix test page (testpage-1div.html) where you can change parameters:

* The content div's ID (divid)
* AMS Base URL (ams) 
* IPS Base URL (ips)
* Activity guid (activity) 
* Assignment guid (assignment)
* PAF repo server name (paf)
  * The activity URL and assignment URL is composed of 
http://repo.paf.{PAF repo server name}.pearsoncmg.com/paf-repo/resources/activities/{guid}
* Course (course) and User (user)

Example:
file://localhost/Users/uahnpyo/workspace/repo/PlayerProto/test/integration/testpage-1div.html?paf=dev&divid=target1

@mlippert , @lbondaryk  Hopefully this is useful to you when testing the 1div contents, If you need, we could add more pages with 2divs and 3 divs.
