• Refactored view indexing:
  • Cursive::find_id now returns a ViewRef, which provides DerefMut but isn't tied to the lifetime of the Cursive root, allowing more natural access.
  • Added Cursive::call_on_id which takes a closure to run on the target view.
• Add mutable on_edit callback to EditView
• event::Event::Unknown now carries the unknown bytes rather than an integer.
• event::Event is therefore no longer Copy
• Add Cursive::focus_id to move the focus to the target view.
• Bugfixes
