Subject: Add option to always show mimetype in viewer

A user may want to be able to see what mimetype they are viewing, so
that they can determine what program it may be opened in or for some
other reason.

The config option is under the [viewer] section and is called
'always-show-mime'. It defaults to false to preserve the current
behaviour.
