Note: the editor portion of this change is to a routine only used by mailnews.

Make mail news handle inline background url styles which is how editor now sets background urls instead of using the obsolete background attribute on the body:

Bug #116867 --> convert background images from file urls to inline cid urls and attach the image as an inline part.This allows thunderbird and mozilla mail to support background images again.

Bug #170504 --> Compose from template/draft containing "Inline Styles" and a background image loses the background image drops the
inline style.
