Fix: delete unused <div>

They are not required and could cause problems,
so better delete those.

Speed up page loading

Speed up page loading just a bit. Also don't convert parameters anymore, let joomla do the job.
Overall function-handling could be improved, but i'm quite satisfied with the result.
