Begun tracking voter info: Added voter schema and successfully tested recording against poll choices. Now need map of ips to names and query to check IP exists before vote on server side.
Minor changes to form helper text to hopefully make usage easier.

Changed timeRemaining method to return moment calendar format.
Changed 'time left' text to 'Poll closes:' plus relative date.
Also added ng-show to show this only while poll is open.
Changes to Gruntfile
