This CL factors EditableString out of EditableText and implements more of the InputConnection functions. As a result, EditableText now basically works. This CL also paves the way to make EditableText stateless by using EditableString as its state object. However, there's still a bit more work to do to make that a reality (e.g., factoring out the cursor blink timer and the connection to the keyboard).
