NotificationMessages set the icon either from the corresponding
notification's gicon property, or fall back to the source icon.
Except that we never actually set a notification's gicon property to
the provided icon, so we currently just always fall back, whoops!
If users click outside the search entry while it's empty we reset and
thus give up key focus. This means that when using an input method
with candidate popups, interacting with the popup with a mouse click
cancels the current input method context if there's no other text in
the entry besides the preedit string.
To avoid this we can check if the entry has preedit in addition to
checking if it has normal text.

Ideally we would allow navigating into the button in the screen
reader case, so the configured clocks are read out properly.
However we can still do better than nothing short-term by pointing
to the section header as the button's label_actor.

Currently both the timestamp and the position in the notification list
are static once a notification has been added; however notifications may
be updated later, in which case those properties should be reevaluated.

On locales that support it, time formats should follow the 12-hour/24-hour
preference, which implies that they should be updated when the setting
changes. So add another utility method which creates a label for a specific
time and keeps it in sync with the format setting.

The world clock uses GLib.DateTime instead of the built-in Date type
because of the much superior timezone support, and therefore cannot
use the new formatTime() helper. To make this possible, modify the
method to support a parameter of either type.

Replace the time formatting in notifications and events with the
new utility method - this makes sure that all times are now following
the clock-format setting and use LC_TIME.
