Feature open poll

Implemented open_vote feature that shows user votes. Can be turned off (default on) by administrator in a plugin settings. When the poll is created and a plugin settings 'open_poll' enabled, creator can select checkbox 'open_poll' that makes all the users' votes in this poll to be shown when displaying results.

Site-wide administrator can view all the poll's votes, no matter of plugin setting or checkbox, by clicking on label (toggles users' votes div) when poll is secret.
