Paul Tagliamonte 41eea22f71 Add two API methods to set RuneBuffer state before prompting the user (#105) 
* Expose RuneBuffer.Set through Operation's API

This allows a user to prefill a line before the user is given a prompt,
so that you can provide a default, user-editable input line.

* Add a Instance.ReadlineWithDefault API method

This will pre-fill the Operation.RuneBuffer with text before prompting
the user, and provide her with a method to edit the provided default.
