Make the message body a public property

[abompard]

The message body property should be public, otherwise schema writers will have to write an accessor for each dictionary entry, which does not make much sense.

I guess we should make a 1.3 release now

[abompard]

Yeah, we should. Do you want me to? Anything else to include in that release?

[jeremycline]

@abompard I can't think of anything. I added some test coverage, so once Travis is happy let's do it.
