Make editing user information more intuitive by adding pop out instead of tab

[jakern]

Current functionality requires admins to search through a user list to find a user and then switch to a separate tab to edit their information. For improved usability we need to add a mouse event listener to the user list table that will launch a new window with editable user info.

I prefer inline editing, but it can be complicated to implement if you've never done it before.
