Make bodies locally toggleable

Having actually implemented this, I realized that my
initial approach of providing a function to configure
a button was wrong. Instead I've replaced that with
button types. This then makes it possible to provide
the fully expanded view when all threads in a message
are unread.

It also has the potential to allow global-expansion functions
if that is desireable
