Making notifications work
Moved notifications into sync service, since truck activity will always be able to receive broadcasts that the sync is finished.
Changes to the notification system:
- check that the progress dialog is not null in the broadcast receiver
- don't include truck stops that have already ended in the notification results
- cancel the notification if it has passed
Changed the color on the separator
Set the notification to auto-cancel
Better documentation
Detect when sync settings have changed and reschedule the sync service
Added "estimated departure time" text.
