Initial concept for shadow user

This initial implementation shows the basic concept of shadowing a user
by showing copies of each input on the form.  Each copied input is then
updated with values as the shadowed user makes changes.
Improved experience for shadow user concept

User now has option to remove a shadow. Elements are not re-cloned when
switching between shadowing users.

Other fixes:
-Removed some console.log messages
-Fixed 'undefined' reference in collidr log messages
-Moved reload warning to after other user has saved an entity
