both admin/user and admin/users working properly. Missing the ability to add groups.
admin/user now includes a group textbox, the group text box uses autocomplete
groups will now save and is editable for admin/user
Removed the ID column from the list of users table
can now go to a specific user and edit them
fixed some stuff
Merge branch 'feature/admin-users' into feature/admin-groups

Conflicts:
	rd_ui/app/scripts/controllers/admin_controllers.js
	rd_ui/app/scripts/services/resources.js
	rd_ui/app/views/admin_form.html
	rd_ui/app/views/admin_users.html
	redash/controllers.py
The admin/users page is now presented in the like of the the admin/groups page
admin/users now has the same upgraded format as /admin/groups, also in both of these there is now a 'View Group' and 'View User' column respectively which allows you to view the attributes of an user or group without being able to edit it
