Title: MathML whitelist adjustments

I've got feedback from Frédéric Wang about our whitelisted MathML attributes. I've added some missing attributes for mstyle and added href for all elements among other things.

I'm not using ALLOWED_ATTRIBUTES.update() anymore (besides for the global attributes for all elements) because it seems to overwrite previously set attributes. Now the list looks much clearer and is probably way easier to maintain.
