[Bug 16932] Add a Cancel Button to the "Changing profile" Dialog in network-admin

[Zakzak]

Public bug reported:

Affects: gnome-control-center (Ubuntu)
       Severity: Wishlist
       Priority: Low
         Status: Unconfirmed


Description:
I accidentally chose the wrong profile and it took like 30 seconds for it to
stop trying to change profile (I'm guessing it was waiting for DHCP to timeout
or something <shrug>).  I would have liked the ability to click a Cancel button
or something to tell it to give up immediately.
