Permissions panel3

Want to get this out there for comments, though it obviously needs more work.  What still needs to be done:
1) Since I changed it to a dialog, I get two icons for adding a person
2) Person lookup needs new view to limit number of fields displayed
3) After entering new person and roles, clicking Add gives stack trace (which *might* be KRAD, I am still investigating)

Since the access dialog can be accessed from any page I believe this binding needs to happen in ProposalDevelopmentControllerBase, otherwise it will only be accessible for action mappings within this controller.
