* Encode the contents of a file for emailing, including headers

* 'contents' - the raw binary contents of the file as a string
* and can optionally include these members:
* 'mimetype' - the mimetype of the file (calculated from filename if missing)
* 'contentLocation' - the 'Content-Location' header value for the file
*
* $file can also be a string, in which case it is assumed to be the filename
*
* h5. contentLocation
*
* Content Location is one of the two methods allowed for embedding images into an html email.
* It's also the simplest, and best supported.
*
* Assume we have an email with this in the body:
*
* 
*
* To display the image, an email viewer would have to download the image from the web every time
* it is displayed. Due to privacy issues, most viewers will not display any images unless
* the user clicks 'Show images in this email'. Not optimal.
*
* However, we can also include a copy of this image as an attached file in the email.
* By giving it a contentLocation of "http://example.com/image.gif" most email viewers
* will use this attached copy instead of downloading it. Better,
* most viewers will show it without a 'Show images in this email' conformation.
*
* Here is an example of passing this information through Email.php:
*
* $email = new Email();
* $email->attachments[] = array(
* 'filename' => BASE_PATH . "/themes/mytheme/images/header.gif",
* 'contents' => file_get_contents(BASE_PATH . "/themes/mytheme/images/header.gif"),
* 'mimetype' => 'image/gif',
* 'contentLocation' => Director::absoluteBaseURL() . "/themes/mytheme/images/header.gif"
