Rename docs/*.md => docs/*.txt

The documentation uses features of Python-Markdown that are not supported on
GitHub and it's better to get a source view of the docs anyway. For example,
that way comments and bug reports can reference a specific line of a file.

Of course, it makes sense for Github to render the README, so that is left
with the `.md` file extension.

-Fenced Code Blocks
-==================
-
-Summary
--------
-
-This extension adds a secondary way to define code blocks which overcomes a few
-limitations of the indented code blocks.
-
-This extension is included in the standard Markdown library.
-
-Syntax
-------
-
-Fenced Code Blocks are defined using the syntax established in 
-[PHP Markdown Extra][php].
-
-[php]: http://www.michelf.com/projects/php-markdown/extra/#fenced-code-blocks
-
-Thus, the following text (taken from the above referenced PHP documentation):
-
-    This is a paragraph introducing:
-
-    ~~~~~~~~~~~~~~~~~~~~
-    a one-line code block
-    ~~~~~~~~~~~~~~~~~~~~
-
-Fenced code blocks can have a blank line as the first  and/or last line of a 
-code block and they can also come immediately after a list item without becoming
-part of the list.
-
-In addition to PHP Extra's syntax, you can define the language of the code 
-block for use by syntax highlighters etc. The language will be assigned as a 
-class attribute of the ``<code>`` element in the output. Therefore, you should 
-define the language as you would a css class - ``.language``. For consistency 
-with other markdown syntax, the language can *optionally* be wrapped in curly 
-brackets:
-
-    ~~~~{.python}
-    # python code
-    ~~~~
-
-    ~~~~.html
-    <p>HTML Document</p>
-    ~~~~
-
-The above will output:
-
-    <pre><code class="python"># python code
-    </code></pre>
-    
-    <pre><code class="html">&lt;p&gt;HTML Document&lt;/p&gt;
-    </code></pre>
-
-Usage
------
-
-From the Python interpreter:
-
-    >>> html = markdown.markdown(text, ['fenced_code'])
-
-
-
