Edit section via Lesson#show player

- Make the player controller manage the state of the edition mode
  instead of relying on the starting player element's dataset
- Listen to the turbo events to change the player mode to edit when the
  sections section is replaced by the section edit
- Listen to the turbo events to reset the player (and the edit mode)
  when the section form is cancelled or submitted (shotgun for now)
