Freeze break request: gnome-contacts

[Alexander Larsson <alexl redhat com>]

I've got a set of fixes for gnome-contacts that I'd like to get in:

https://bugzilla.gnome.org/show_bug.cgi?id=659624

This adds keyboard shortcuts for quit and focus-search so that we have
the same behaviour as gnome-contacts. Not super-important but quite
safe.

Make sure error dialogs close on OK.

GtkGrid behaviour changed, so our spacing is totally wrong. This fixes
that back to how it used to look.
