utils: Add body() and document_element() getters

[jplatte]

Closes #160.

Can you release #159 and this in gloo-utils 0.1.1 / gloo 0.4.1 after merging? :)

I think adding functions should be a minor version increase and not a patch version increase. Isn't it a little too early for another one of that release

That logic makes sense after 1.x but I wouldn't consider new features before 1.x to always require breaking-change releases, so the only option would then be to do a "patch" release (not sure whether I'd even call it that).

I agree. I'll update Yew and if nothing else comes up, I'll publish a new "patch" release

@jplatte done!

Sorry it took me almost a month.
