Repeater templates shows up in page settings for superusers

When changing template for a page in the page editor ProcessPageEdit, repeater templates show up in the template list.

Here's the relevant forum discussion
Also: #287

Optional: Suggestion for a possible fix

Superuser or not repeater templates shouldn't be used anything other than repeater items. Since repeater items are assigned their template using API, and these templates are used for nothing else, they shouldnt show up at all.

Here's a possible fix:
