Add Share Sched.do modal after a user votes on an Event

* Add modal to the event show screen that opens on vote click
* Add new configuration options to the Yammer Autocomplete widget
* Rename auto sync and sync translators to names that are more specific to their use cases
* Added a new function to the YammerApi object for delivering group messages
* Extracted request and render javascript messages out of translators into their own objects.
* Use newly extracted request and render functions as building blocks for translators to make for easy reuse (kind of DCI-ish)
* Remove repeated style definitions
* Add jasmine gem to make it easier to get detailed JS test failure information
