Fixes github#463

Closes github#497.

Fix a couple of RST issues

upgrade to Asciidoctor 1.5.2

This addresses issue github#514.

Previous behavior was to silently ignore unknown directives and
comments, which made .rst documents that utilized rst extensions
appear to be incomplete.  This fix allows all the information to
be displayed, and further allows comments to be placed to indicate
that the github rst viewer is not the preferred viewer for the
document.

This patch will not alter the appearance of any document that
is specifically coded for display at github which doesn't use
restucturedText comments.

Additional possible enhancements include figuring out how to
gray out this text, and/or to support a special github directive
at the start of the text file that controls whether this new
behavior is enabled.

Also add test file to show new operation.

My docutils configuration must be slightly different than github's.

Add code of conduct to contributing guidelines

Resolve issues with the `tt` tag in MediaWiki

Many Python projects use Sphinx to create documentation from .rst markup.

Using a doctest:: directive the markup can include blocks of code that is both
tested and rendered in the final documentation. These blocks are not rendered
on github.com though, e.g. in a README.rst.

To remedy this (without adding Sphinx as a dependency) this PR aliases
doctest:: directives to code:: directives,. The language of such blocks is set
to 'python', since doctest only supports Python.

Refs dateutil/dateutil#83

Added doctest blocks to reStructuredText (with tests)

Conflicts:
	lib/github/commands/rest2html

useful for prepare for printing multiple documents:
github-markup repo/docs/*
instead of
echo repo/docs/* | xargs github-markup

This code will keep current behavior for python 2.x.

In that docutils version, HTMLTranslator.visit_image no longer appends
empty string to self.context, so trying to pop() from there raises an
IndexError.

Instead of the hard-coded pop call, call the overridden method, which will
call pop() on docutils 0.12 and will do nothing on docutils 0.13.

Fixes github#971.

Also, fix the comment indentation.

…inal

Simpler to just pipe the result of each command to the next.

This changed at some point recently. (My system docutils wanted to do
this, but the current latest on PyPI (0.13.1) doesn't.)  This is an
old-style object (!) so we have to use this hack.

Bring github#241 up to date
