Add a few basic Jasmine tests

* SpecRunner-Player runs some basic tests on the player
* SpecRunner-CreateRemove tests for Issue #670

Note: the tests run directly on the individual .js files rather than
on the catenated or minified files.  That could be easily changed,
but it's nice to be able to run a test, make a fix, and just reload
the browser.

SpecRunner-CreateRemove.html currently has one test that fails because of Issue #670
