Changed "Repeat Rule" to "Date: Repeat Rule" in the feeds sources list.

This makes it consistent with the "DateField: Repeat Rule" feeds target
offered by the Date module. It also pushes the source up next to the
"Date: Start" and "Date: End" sources, which helps you find it when you're
setting up your mapping.

This is only a UI change.
