Bug 9439 - Enforce superlibrarian mutual exclusivity of other permissions

Basically, when you check the checkbox for the superlibrarian permission
in the patron record, it will disable and uncheck all the other
permission checkboxes. When you uncheck the checkbox for the
superlibrarian permission, it will renable those boxes. There is also
some JS code there to ensure that the other boxes are disabled when
returning to the change permission screen (i.e. the patch is not just a
click handler).

In the event that the checkboxes for superlibrarian and other
permissions are already checked, the user will be shown a pop-up window
explaining that the superlibrarian permission is mutually exclusive to
the others (since it already includes the others) and that the
permissions for that patron will then be reset to just include the
superlibrarian permission.

Comment: Tested on master. Works as described.
