Whole bunch of tiny tweaks, some important

Big stuff:

1. Multiple notifcation plugins now work. 
2. Alternate emails work. 
3. Disabled subscriptions no longer alert. 
4. Graphite targets with alias(foo,"bar") will work. 

Little stuff:

clearing alerts doesn't say it's deleting, it says its acknowledging. 

Users can always access their settings, admins can access system settings as well. 

Large targets will scroll.
