Patch

This patch restores foreign content in mtext/mn/mi for phrasing content:
http://www.w3.org/TR/html5/dom.html#phrasing-content-1

The case of mo is a bit tedious, so it is not handled here. Anyway, the HTML5 validator currently only allows foreign content in <mtext> so that's what people are going to use in practice.

I also tried to restrict the content of annotation-xml to Flow content + <html> as indicated in the RelaxNG schema, but that breaks some tests relying on foreign <mtext> and it is a bit difficult to keep perfect rendering matching otherwise. So I finally didn't change what annotation-xml accepts. http://www.w3.org/TR/html5/dom.html#flow-content.

This should hopefully make mspace-units pass again.
