[PATCH] emacs: content-type comparison should be case insensitive.

[Mark Walters]

The function notmuch-match-content-type was comparing content types
case sensitively. Fix it so it tests case insensitively.

This fixes a bug where emacs would not include any body when replying
to a message with content-type TEXT/PLAIN.
