Generally use reliable shutdown method and test shutdown applet separately.

Sometimes Sikuli fails to find the shutdown icon in the shutdown
applet's menu (possibly because it's covered by a notification) so
that method isn't completely reliable at the moment. To contain this
problem we test the shutdown applet separately, and rely on the more
dependable remote shell for halting in the general case.

While we're at it we also make sure that the shutdown steps are
formulated so what they do is more explicit.
Remove FIXME; #5972 has been fixed.
Bump max_coverage.

It has been reported that the old value sometimes fails for the
"Memory erasure on an old computer" scenario. 0.5% is still a clear
indication that significant wiping was successful. Also see #7313.
Bring back check for "Tor is ready" notification.

The Sikuli images are now updated for Wheezy.
Bring back check for Unsafe Web Browser notifications.

The Sikuli images are now updated for Wheezy.
Make Unsafe Web Browser notifications work again.

Running `notify-send` as root doesn't show anything, so we fallback on
our reliable `tilas-notify-user` instead.
