+ Extend body parsing capabilities to match with imap_fetchstructure

[dicode-nl]

I've extended the BodyStructure.php to be able to parse more different message types and match output with imap_fetchstructure. Tested with over 2000+ messages

This code works beautifully and fixed the issues we were having with duplicated html body, and attachments not being assigned properly. Thank you!

@Orgoth can't this be fixed in a single statement like the rest of the base types

            if (is_scalar($item) && strtolower($item) == 'signed') {
                $subType = 'SIGNED';
                $section = 'parameters';
                continue;
            }

@Orgoth could you send me the json for fromBodyStructure so I can run it trough the parser?

[dicode-nl]

Seems legit to me, pushed the changes to this PR.

@Orgoth how about this version, it is more in line with the original c-client parsing which is used by php_imap

@dicode-nl So far this is working as intended! Fixed a bunch of issues I was having. Great work!
