Make bibtex converter use configured filters.

The bibtex converter class was not making use of the `bibtex_filters`
global configuration option.

Add filter for \superscript LaTeX command

This filter converts \textsuperscript latex formatting into <sup> html
tags. It should be used before the `latex` filter to prevent premature
stripping of {} groups.

Also adds superscript to the default filters and documents the
bibtex_filters parameter in README.md
