[PATCH] emacs: show: make RET always toggle parts where plausible

[Mark Walters <markwalters1009@gmail.com>]

This makes RET toggle the visibility of any part which has a component
that can be displayed in the buffer. This included text parts (plain/
html/ x-tex etc) and images. Parts which cannot be displayed (eg pdf)
RET acts as before and saves/views etc.

Definite actions can always be accessed with s,v and o (eg v to view a
text/html part in a browser).

This is a slight tweak at Jani's suggestion on irc. Applies on top of
the previous series.
