Resolves Issue #47.
+ Added a DisplayMath/InlineMath selector to Math inlines.
+ Markdown parser yields DisplayMath for $$...$$.
+ LaTeX parser yields DisplayMath when appropriate. Removed
mathBlock parsers, since the same effect is achieved by the math
inline parsers, now that they handle display math.
+ Writers handle DisplayMath as appropriate for the format.
+ Changed -m option to use LaTeXMathML rather than ASCIIMathML.
LaTeXMathML is closer to LaTeX in its display of math, and
supports many non-math LaTeX environments.
+ Modified HTML writer to print raw TeX when LaTeXMathML is
being used instead of suppressing it.
+ Removed ASCIIMathML files from data/ and added LaTeXMathML.
+ Replaced ASCIIMathML with LaTeXMathML in source files.
+ Modified README and pandoc man page source.
+ Modified web page.
+ Added --latexmathml option (kept --asciimathml as a synonym
for backwards compatibility)
+ Modified tests accordingly; added new tests for display math.

+ No space between paragraph and following @verbatim (provides more
pleasing appearance in text formats)
+ Blank line consistently after list environments.
+ Removed deVerb.
+ Use @code instead of @verb for inline code (this solves the character
escaping problem for texi2dvi and texi2pdf).
+ Modified test suite accordingly.
+ Added Peter Wang to copyright statement (for Texinfo.hs).
+ Added news of Texinfo writer to README.
+ Added Texinfo to list of formats in man page, and removed extra 'groff'.
+ Updated macports with Texinfo format.
+ Updated FreeBSD pkg-descr with Texinfo format.
+ Updated web page with Texinfo writer.
+ Added demos for Texinfo writer.
+ Added Texinfo to package description in debian/control.
+ Added texi & texinfo extensions to Main.hs, and fixed bug in determining
default output extension.
