control-center freeze break

[Matthias Clasen <matthias clasen gmail com>]

Hey,

I want to commit https://bugzilla.gnome.org/show_bug.cgi?id=672445 for 3.5.91
It makes the map widget appear insensitive when you can't interact with it.
I don't think this affects the docs - I haven't seen any datetime
panel screenshots in there.

I'll give myself the first +1 for the release team.
