Version 2.2

* Globalized the $homepoll variable on the Standard Edition. Now you can
add the poll to any page of your forums by placing "{$homepoll}" in any
template (with some exceptions, including the header template). By
default it still only displays on Index and Portal, and display on those
pages can still be enabled/disabled in settings.
* Improved the way the redirect back to the page where a poll action was
taken is handled. It should now work on any page of the forums without
issue. However, the redirect after editing a poll has been removed
entirely. That implementation was more complex than I felt was worth to
keep it around.
* Fixed an issue where the pollbar graphic wouldn't appear on the Show
Results page on the ASB Edition.
* Cached the version number to make future upgrades easier (Standard
only).
