Screen off: stop polling for now playing info.

If the user wants "Now playing" info to appear in their notification
area, make sure we don't poll XBMC every second while the screen is off,
as any new information cannot be seen until the screen is turned back on
anyway.
Fix import
ported code from hjhamala to stop now playing poller when no subscribers
Avoid NullPointerExceptions in empty sections

When a section is empty, the result list is omitted from the Json but
the Json result still contains a "limits" element. Thus checking for
result.size() == 0 is not robust enough. So check for the actual list
element to exist.
Handle empty playlists correctly

Do not throw NullPointerExceptions and
IndexOutOfBoundExceptions when retrieving an empty
playlist.
