Inline Edit: Suggest paths to add

Offer a suggestion box completing any known file path in the
repository whose path name contains the letters offered by the user.
E.g. "AddFile" would suggest the first three files of this change.

Instead of loading content into a small primitive text area, load the
file into an EditScreen where CodeMirror is configured.  This makes it
easier to begin editing the file right away and do something useful
with it.
