The use of `nodeValue` on `Attr` objects causes a deprecation warning in
Firefox since version 7. This patch causes calls to `value` instead of
`nodeValue` for all `Attr` objects.
This closes#362.
* Added data/MathMLinHTML.js, which is included when no URL is provided
for --mathml. This allows MathML to be displayed in better browsers,
as text/html.
* The module was no longer necessary; its functionality (two lines)
was incorporated into pandoc.hs.
* Consolidated the two LaTeXMathML.js files into one.
