This was a hack added for libhandy-0, which is no longer required.
Also, this hack results in the switch not working when gtk animations
are turned off.
AdwActionRow handles many of the properties we use
CcListRow for. We can re-use it instead of re-creating it.
CcListRow is now an AdwActionRow with three suffixes.
The `activatable-widget` is set when the switch is visible.
Since our `icon-name` property was only used for the arrow
icon, it has been replaced with a `show-arrow` property.
The `bold` property has been removed - it was only used in
one place, and it's not a pattern used in other apps.
I decided to go this route because replacing all the
instances of CcListRow with AdwActionRow directly would
end up being more code.
This is only the bare minimum to make everything under panels/common
build. Since these widgets are used by the main window, port them
first.
CcTimeEntry was particularly hard to port. That's because GtkEntry
is a final class now. Overall, though, I'm happy with how it turned
out to be - much cleaner, less code, more obvious.
