The previous commit removed default-valued properties,
but apparently that has a negative effect for grid
packing properties, so put the explicit value back.
Add a button to allow restricting search to the current
folder (and subdirectories). This makes the search more
useful, and makes the file chooser more similar to
nautilus.
In search, we show files from differnt locations, and it makes
sense to show where they come from. This makes the file chooser
more similar to nautilus, too.
The last round of filechooser redesign work had left
search somewhat dysfunctional. This commit fixes things
up enough that search is once again a working feature
of the file chooser.
Most of the core GNOME applications (eg., gnome-control-center,
gnome-documents, and nautilus) start searching as soon as the text
changes, and don't wait for the user to hit ENTER. It would be nice to
follow the same pattern.

This subdirectory gets in the way when integrating the inspector
build more fully with GTK+, and does not really add anything.
Just move everything one level up.
