[PATCH v2] emacs: show: stop display of application/* parts

[Mark Walters <markwalters1009@gmail.com>]

Gnus seems to display application/zip and application/tar by
default. This doesn't seem desirable so we override it.

We only override if the user has not customized
mm-inline-override-types themselves.
---

I think this fixes all the bugs (and typos). Thanks to Tomas and Tomi
for finding and verifying the correct way to get the default value of
a defcustom variable.

It's only lightly tested but seems to work.

Best wishes

Mark
