Add changed discussed with John on Friday (use session->flashdata for alert block, rewrite functions to not use  directly, etc). Also added display of percentages to poll results. Main TODO left: Ajax!
Tested out all functions to make sure everything really was still working. It now is. *NOW* we start AJAX
renamed helper file since it is my own helper file.
Got AJAX working for voting and result display. Changed point at which I called my custom helper so that it is available to the whole controller and views. Moved some functions from Poll model to Poll Controller. Added jQuery to project because of sketchy internet issues.
