Disallow custom HTML in file info format.

I doubt anyone is using it, and if someone manages to inject a
malicious script into the page, this could be used to install a
script permanently to be executed each time 4chan is visited.

I'll mention it in the changelog, and if anyone complains, I can
add it back with some security checks.
Drop HTML in custom board titles.

This could be useful, but the fact that it's been broken almost
since its creation indicates nobody's actually using it.

As with the file info formatting, I'll mention it on the changelog
and add it back with better security if someone actually wants to
use it.

Change order back to that of Mayhem's list.
