Corrected null exception error when updating a new meeting's speakers.  Added IsOver() method to make checking if the event has ended faster.
Updated the layout of the speaker list to not include a link if you are currently viewing that speaker.
Removed the cancel/back to index paths.  They are a bit antiquidated and should be burned in the hottest pits of hell.
Renamed the list of speakers from "Presenters" to SpeakerList.  This should correct the issue where the speakers who were selected were not being set as selected on edit or validation pages.
Added logic to remove the links to RSVP or add a ended event to the calendar.
