Not all messages can fit on the current screen in sms conversation windows,
so there may be some holes that might suggest that there are no more messages
to display. Now, when therea are more SMS to see by scrolling up,
the Old Messages label will indicate this fact.
Fix of the issue that pressing up arrow in
empty list (e.g. notes, messages, alarms)
resulted in unnecessary deep refresh of
the screen, as the content didn't change.
Split module-utils into smaller components for better dependency
management. Fix many dependencies throughout the project.
