Document type layout of str #410

[Zaechus]

I documented the size behavior of type str to the 9.3.Type Layout section.
Fixes #410

Can someone please review my pull?

Is this any better?

Hm. I think this is ok, but we can do better. Since str is a slice type, I think that mentioning it in the slice section might make more sense, and then call out that it's a UTF-8 representation of its characters. As is, "each character" is kind of vague, and I don't think we need to duplicate the array section which goes into more detail. Really, str is just [u8] with an additional guarantee that it's valid UTF-8.

Can you please rebase this on top of HEAD to remove the merge commits? Otherwise looks good to me.
