Panlunatic filtering: modifying documents without external software

[Albert Krewinkel <albert+pandoc-9EawChwDxG8hFhg+JK9F0w@public.gmane.org>]

Hello,

writing maximally portable filters is difficult, as filters always
require additional software to be installed next to the pandoc binary.
In certain cases, this might make it impossible to use filters in
collaborative writing. I wrote a custom [panlunatic] writer, which
outputs JSON. This makes it possible to perform some minor modifications
to the document using lua, and without the need for additional software.

The script is very limited and far from exposing a user-friendly API in
the style of panflute and friends: If you want to modify an element,
you'll currently have to decode the element's JSON representation,
modify the resulting table, and re-encode the result to JSON again. It's
as ugly as it sounds. I plan to implement a nicer API in the future.

The project is in very early alpha state.  Feedback, criticism, or pull
request are welcome.

Cheers, Albert
