Bumped timeout

I've found in opera that copy+paste doesn't work, so I have to drag and drop. Additionally, we need
the user to have time to read and comprehend what we're telling them before this notification
disappears forever.

Despite the fact that this is technically a configuration bug on the sys admin's part, for a future
release, we should switch to a different type of notification, probably like a banner with an X that
they can close once they're done reading it. That way we know it'll be there as long as they need it
to be.
