Handle inline tags that span multiple lines about sphinxify HOT 4 OPEN

The problem here is that the <strong> spans multiple lines. I'm not sure how easily we can fix this.

So there are :strong: and :emphasis: roles, and roles can span multiple lines, so doable. IMO RobotPy should use :math: roles where appropriate though.

I'll handle sub and sup tags as well.

Hmm. How do you nest bold and superscript in rST?

… that is definitely not nice. I'm just not going to handle nesting.

We could probably do with a way to warn about this from robotpy-build, but, uh, future work?
