Show creation date on poll pages

[alyshkalia]

It would be great if the main page for a poll shows the date that poll was created. Right now the only way I know of to see the date is on the "browse polls" page (https://ifdb.org/search?browse&poll&sortby=new); it would be nice if it was shown on each poll's page as well, because it's helpful to know if a poll is recent or years old.
