#56578 Path to include style.css does not handle subdirectories

#50390 (partial) Body gets truncated in plaintext mode

Apparently, url() expects a path only.  For non-clean-urls, _mimemail_url() was appending an additional "?q=".For now, let's just remove the original '?q=' and send only the path to url()

evidently, theme_add_style() now returns an object.  Use correct datatype in theme_mimemail_message and filter out non-screen/all css files

Content-Type headers (Evidently, it's assuming the part is an attachment)

Remove the 'name' attribute from the text/html part.

set plaintext portion to utf-8

make inline attachments -> content-disposition: related

version of mail.inc
