shell freeze break request

[Ray Strode <halfline gmail com>]

Hey guys,

There are a few bugs that I think would be really worthwhile to get in
for a better 3.2 login story:

Fingerprint reader support for login.  We had this feature in 3.0, but
I didn't get it added in the initial cut of the shell based greeter.

Shutdown menu.  The initial design for the login screen lacked a way
to power off the machine (without first logging in).  Given we've
historically told people one way to power off the machine is to first
log out, this is kind of contradictory.

Logo.  The old fallback login screen has a way to specify an optional
logo at the login screen.  This was added for site administrators to
brand their lab machines, and distros also use it to add branding.  We
don't want to show any sort of logo by default, so this one would only
get shown after changing a gsettings key.

Thoughts?
