Improve scripting around adding people to things
Use the post type slug for retrieving all object data

This makes things easier to handle all around. Not sure why I
tried to mask it originally.
Track IDs of people added in a hidden input for saving
Flush data around people, entities, and projects as they are saved
Save associated people to objects, display currently associated people
People can now be unassociated from obects
Extract inline styles to a proper admin stylesheet
Use array literal
Move Javascript from inline to an admin JS file
Add missing stylesheet to repository
Abstract people JS to work with all of our object types
Check for a defined object before defining wsu_uc
Setup the projects meta box in anticipation of abstraction

This is fairly temporary. Now that things are together, they can be
abstracted for better long term management of object types
