Fixed bug in the wizard where, if more than one Recurring Calendar Event was created, only one would succeed.
Was caused by all frequency radio buttons having the same name, which means when one asset's recurrences were clicked, it would remove all selections from the others.

So:
- Renamed the radio buttons with their queue numbers so they were grouped properly.
- Added a fieldset around them with a class name.
- Used the fieldset as a target to find the appropriate recurrence selected in the wizard gather create data decorator.

Fixes SM#3689.
