* Update Project workflow now includes a tab to update project members
* Can add/remove existing users from project and update roles
* Can add a new user via inline object creation
* Can filter both lists!
* Changed css/jquery to make things appear more like other tables
* Fixed a few JS bugs
* "Fixed" exception handling for now, although it naively redirects the
user out of the workflow
partially implements blueprint tenant-creation-workflow
