Task and routine sorting buttons do not update

[svetogam]

The "Move Up" and "Move Down" buttons for tasks and "Move Left" and "Move Right" buttons for routines often do not update their disabled/enabled status immediately. This opens up the "advanced speed tech" of making a task or routine wrap around from the top to the bottom, which is too fun and so should be removed.

Cases:

• Routine Builder screen:

  • Add Task does not update the Move Down button on the previously last task.
  • Paste Task does not update the Move Down button on the previously last task.
  • Delete Task does not update the buttons on tasks around it.
  • Pressing the Move Up or Move Down on one task does not update the buttons on the task it switches places with.

• Routine tab of Main screen:

  • Adding a routine does not update the Move Right button on the previously last routine.
  • Duplicating a routine does not update the Move Right button on the previously last routine.
  • Deleting a routine does not update the buttons on the routines around it.

The solution that comes to my mind is to emit task_list_changed and routine_list_changed signals, and then connect these to updating the buttons. That way you don't have to think about when exactly which buttons should be updated.
