Jasmine: a re-config, an upgrade, and a hack

* We don't need to explicitly include `jasmine-jquery.js` in the `specs/javascripts` directory if we reference it properly in `jasmine.yml`
* update to the newest version of `jasmine-jquery-rails`
* Gmaps4rails 1.5.6 conflicts with [something] in such a way as to cause `rake jasmine` to run multiple times, attempting to run multiple jasmine servers on the same port, causing it to crash. The fix is to upgrade gmap4rails. The bandaid is to have jasmine handle this error by exiting all servers once it successfully passes.
