Bugfix Joomla module slide show

This bugfix only contains two minor adjustments to the module’s admin interface:

1. The four parameters that must be inserted have been placed to the top of the interface, instead of in the middle and at the end. Much more logical, of course.

2. The label of the ‘number of slides’ parameter erroneously said ‘wait’. Now it says ‘number of slides’.

So there is no reason to update to this version if you’re happy with the previous one.
