MIME variables

[Lars Magne Ingebrigtsen <larsi@gnus.org>]

I think the following should reflect the state in 0.91:

Customization
=============

`mm-inline-media-tests'
     This is an alist where the key is a MIME type, the second element
     is a function to display the part "inline" (i.e., inside Emacs),
     and the third element is a form to be `eval'ed to say whether the
     part can be displayed inline.

     This variable specifies whether a part _can_ be displayed inline,
     and, if so, how to do it.  It does not say whether parts are
     _actually_ displayed inline.

`mm-inlines-types'
     This, on the other hand, says what types are to be displayed
     inline, if they satisfy the conditions set by the variable above.
     It's a list of MIME media types.

`mm-automatic-display'
     This is a list of types that are to be displayed "automatically",
     but only if the above variable allows it.  That is, only inlinable
     parts are usually displayed automatically, but in the end, this is
     up to the display agent that's using the MIME library.

`mm-attachment-override-types'
     Some MIME agents create parts that have a content-disposition of
     `attachment'.  This variable allows overriding that disposition and
     displaying the part inline.

`mm-discouraged-alternatives'
     List of MIME types that are discouraged when viewing
     `multipart/alternative'.  Viewing agents are supposed to view the
     last possible part of a message, as that is supposed to be the
     richest.  However, users may prefer other types instead, and this
     list says what types are most unwanted.  If, for instance,
     `text/html' parts are very unwanted, and `text/richtech' parts are
     somewhat unwanted, then the value of this variable should be set
     to:

          ("text/html" "text/richtext")

`mm-all-images-fit'
     If non-`nil', all images will be deemed to fit into the buffer,
     even when they don't.
