Reimplement editor_prompt and 'Save as' using the new prompt modeHEADmaster

Now there there is a new way to prompt for text, we can reimplement the
long abandoned editor_prompt function and use it to allow saving to new
files.

The new editor_prompt function takes a callback that will be called
after the user presses enter on the prompt.
