Previously the entities and navigation are entangled inside a common
DOM structure which limits code reuse. Now they have been moved
into separate structures.
The IPA.dialog has been modified to support sections. The add
dialog for permission has been modified to include the target
section. The base dialog classes have been moved from widget.js
into a new file called dialog.js.
This patch also includes ayoung's fix for parameter name and
format for the permission attributes.
