Authoring: smaller sizes for name fields on nodes and links.
New Feedback Rules.
MySystem.activityController : contentFromWiseStepDef defined here now.

This used to be defined in the model MySystem.Activity.
The controller is a better place for this sort of thing.
authoredContentDataSource is a MergedHashDataSource. (delete works now)

SC.BUSY errors happened anytime the PaletteItems were destroyed.
Why?  Because they didn't have a real datasource.

Same for RubricCategories and friends.
