Enable backgrounding a single <mail> function.

Backgrounding exits to the index menu.  Re-invoking <mail> will resume
the backgrounded session, if one exists, otherwise start a new
session.

This is just to get basic support going.  Multiple background edits, a
landing page, a background compose menu list will be added next.
