An option to allow thread creators to edit the poll options.
From the Admin CP, admins have the option to either allow or not allow this option to appear when creating a poll, for thread creators (normal users). They can restrict it for a particular forum section only (if they want).
Currently, this is not allowed: http://prntscr.com/4a4gya
There are 'game threads' where the moderators and player KNOW the poll needs to be edited. Hence why, for some sections, this option will be useful.
