The easyrtc.js client used to be a single easyrtc object that was created at run time.
This has been replaced with a Easyrtc constructor object from which an easyrtc object is built.
This was done to clean up some private variables and methods that shouldn't be exposed in the easyrtc object.
It will also allow you to creae a second instance of the Easyrtc object that ran concurrently or successively with the original.

This change should have no noticeable impact on anyone who includes the easyrtc.js file itself.

If you are including easyrtc_int.js, you'll need to include adapter.js first (that's been factored out) and change your
   easyrtc.constant_strings  = {...}
to
   easyrtc_constantStrings = {...}
