Ensure ACTION_VIEW/ACTION_EDIT Intents only resolve to Contraction Timer's package
Adds TAG constants to use for logging
Adds debug logging to NotificationUpdateService
Log Up button presses on all activities
Use getSupportParentActivityIntent to build Up intent for EditActivity

Instead of attempting to handle the Up button ourself, use the getSupportParentActivityIntent to build a custom Up Intent for the Edit Activity (which can lead both the MainActivity when in 'Add Contraction' mode and ViewActivity when in 'Edit Contraction' mode).
Change EditActivity's title to Add Contraction in Add mode
