Markdown2

- ["toc" extra] Unescape Markdown special chars in TOC entries. See
<https://github.com/trentm/restdown/issues/15>.

- Now 'tox' testing support (by github.com/msabramo):

[sudo] pip install tox
tox

confirming that markdown2 works with jython (not sure which version) and
pypy! Also added pypy to travis-ci testing
(http://travis-ci.org/#!/trentm/python-markdown2).

- [issue 90] Add a `Markdown.preprocess(text) -> text` hook for subclasses.
This is a match for the `Markdown.postprocess(text) -> text` hook added in
an earlier version. (by joestump).

- [issue 90, backward incompatible change] Require a space between the ''
and a text for a title. I.e.:

This still works

This doesn't work

Nor this

This keeps comments, hash tags, and ticket numbers at the beginning of the
line from turning into an h1. (by joestump)

This is a backward incompatible change, however small, hence the version
change to 2.0.0.

- [issue 84, issue 87] Fix problems with fenced-code-blocks getting
double-processed.

- [issue 67] Fix an sub-`ul` inside a `ol` not working with an indent less
than 4 spaces.

- Fix code blocks and fenced-code-blocks to work with a single leading newline
at the start of the input.

- [issue 86, 'fenced-code-blocks' extra] Fix fenced code blocks not being
parsed out before other syntax elements, like headers.

- [issue 83, 'fenced-code-blocks' and 'code-color' extras] Allow 'cssclass'
code coloring option (passed to pygments) to be overridden (by
https://github.com/kaishaku). E.g.:

import markdown2
html = markdown2.markdown(text,
extras={'fenced-code-blocks': {'cssclass': 'mycode'}})

- [issue 64] Python 3 support! markdown2.py supports Python 2 and 3 in the
same file without requiring install-time 2to3 transformation.

- [issue 80] Jython 2.2.1 support fix (by github.com/clach04)
