Several editor fixes (#1478)

* Declare toolbar api via modifiable property

* Fix addon buttons

* Assign editing areas in a synchronous way

* Restore the Tab shortcut that moves the caret to end

- moveCaretToEnd is called twice now: The moveCaretToEnd calls in
  *TextInput causes the caret to be moved to the end when switching back
  from the window and back.
- To fix this, I will need the code for saving and restoring locations
  from #1377

* Restore selections in the PlainTextInput

* Improve type safety of destroyable

- clearable-array was renamed to destroyable
