Ideas for a better Editor

[sallesma]

• [x] Save automatically every action, no need for an explicit button for this
• [x] Rename a drill in place instead of opening a modal ?
• [x] Rename a drill directly from the drill list
• [x] Make the drill list more visible. The icon is a bit hidden among the action toolbar
• [x] Land on a PlaybookPage from the Home with the list of plays, and then select a play (or create a new one) to use the editor
