Title: Changed attached diff Content-Type to text/x-diff

Some mail readers (such as mutt) rely on the Content-Type rather than
the file extension in order to determine the type of an attachment.
This commit sets attached diffs to use the far more descriptive
text/x-diff content-type, rather than text/plain.
