Make email body processing easier

[baudehlo]

Everyone seems to stumble when processing mail body text with Haraka.

The problem is Haraka presents a raw version of the MIME structure tree to the developer. Most people just want the visible text and/or html part, not mess around with the tree structure.

We should have a library (or function) that makes it easier to traverse the body parts and extract the required information.

This would be great. It's definitely something I stumbled around with for a while.

this is an good idea, is it always in the first tree?

@baudehlo , "add get_body_html() and get_body_text() functions"

[KingNoosh]

Is this still wanted? If so I can take a look at this!

[msimerson]

Yes, else we'd have closed the issue. :)
