Fixes #198

Previously, html-like content would have to be run through Format::htmlchars
before being passed to Format::sanitize, because things that looked like
invalid html content would be removed.

email: Accept inline body with disposition params

Reviewed-By: Peter Rotich <peter@osticket.com>

A mail client may indicate a header parameter (such as Novell Groupwise,
which may add something like

Content-Disposition: inline; modification-time: "Thu ..."

) Previously, the system would not consider the content to be a candidate
for the email body, because it has parameters to the content-disposition
header.

This patch will still consider the part to be a candidate for the body if
the mime types match and no filename is found in the content-disposition
parameters.

Handle cases where email headers contain unicode or high-ascii characters
and are not encoded according to RFC-2047. This patch handles a special case
where a detectable unicode character set is used, such as UTF-8. For
high-ascii characters in a character set other than iso-8859-1, the result
of this patch is undefined.

Fix attachment mishap in outgoing emails

Reviewed-By: Peter Rotich <peter@osticket.com>

The detection of inline images in the mail processor causes inline images to
be removed from the attachment list, if listed there. However, the
attachments in the attachment list were not keyed by the attachment-id, so
there was no proper way to detect and remove the attachments from the list.

This patch properly keys the attachment list by the attachment file_id
