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

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

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

This was mentioned on irc today and this might be a reasonable way of
doing this.

It does mean that if a user adds, for example, image/* to
mm-inline-override-types then application/* will be displayed again.

It also makes it slightly awkward to allow all types (eg setting
mm-inline-override-types to non/existent would do).

Also I feel there ought to be a better way to tell if a variable has
been customized (or otherwise set), but I didn't find one.

Best wishes
