[TASK] Simplified config handling for template file
[BUGFIX] Fixed one vote label
[TASK] Removed "L" GET parameter

This parameter should be automatically added with the config.linkVars
setting.
[BUGFIX] Voting for multiple polls

Fixed voting for polls that are diplayed on a page with multiple active
polls. The uid parameter is now appended to the poll form so that
votes can be counted for more than one poll.
[TASK] Simplified finishing of poll submit

At the end of every poll submit the user will be redirected either to
a configured page or to the current page requesting the result view
of the poll.
