Keyboard navigation in Message Windows patch.

["Jesse D . Sightler" <jsight pair com>]

This little baboon wart allows you to use the keyboard navigation keys
to move up and down while reading email.  Implemented are the arrow
keys, PgUp, PgDn, Home, and End.

Note that there is almost certainly "A Better Way" (TM) to do this, but
this works here.  :)
