Method to get all text parts and complete text body

[arwinvdv]

I tested the library with a mail with 2 attachments send from an iPad. But I didn't get the right body because of multiple plain text parts.

I added the getCompleteBodyText function to get all plain text parts as one string.

Shouldn't getAllContentsByType be called getAllContentsBySubtype since it checks for subtypes. I would use it to find the DELIVERY-STATUS AND RFC822 attachments, which are subtypes. Maybe it's too verbose, but more clear IMO.

@rudiedirkx can you test this patch to see if it solves #561?

It doesn't. It can't because the problem lies somewhere else, in 'attachment detection' in AbstractPart::lazyParseStructure() and/or AbstractPart::isAttachment(). It's not about finding the right part. That's already possible with new RecursiveIteratorIterator($message, RecursiveIteratorIterator::SELF_FIRST). That could be made much easier in this PR with a getAllPartsBy(Sub)type, but that's more for me than for this PR.

Hello, can you return subtype SUBTYPE_RFC822 along with SUBTYPE_PLAIN in getCompleteBodyText message/delivery-status is a subtype used by gmail to return extended smtp error code
