Ability to clone User Groups

To control what variables and events are shown, we have Virtual Report Suite specific user groups set up.

Currently when we need to set up a new user group, it's insanely time consuming to add users to the new group because the pick list only includes the username, no other attributes. 

Two features that would address are issue are:

1) A user group cloning feature (e.g. through a 'copy' button or a Save As) would allow us to set up a master user group that contains all the users and the we clone it to adjust the 'report access' customizations.

2) Add the ability to search on any user attribute, not just username, on the user group screen. This would allow us to store values in their profile (e.g. title since there's no general description field) that are helpful for the way we organize our user groups.
