Add a footer region which contains essentially the playback and frame
range buttons from the Timeline Editor, to the following editors:
- Dope Sheet
- Graph
- NLA
- Sequencer
Available in the View menu in each editor, hidden by default.
The motivation is to provide a convenient way to access these
often used controls, and in the near future adjust these footers
to add more playback functionality related to each editor.
