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.

-Sane Lists
-==========
-
-Summary
--------
-
-The Sane Lists Extension alters the behavior of the Markdown List syntax
-to be less surprising.
-
-This extension is included in the standard Markdown library.
-
-Syntax
-------
-
-Sane Lists do not allow the mixing of list types. In other words, an ordered
-list will not continue when an unordered list item is encountered and
-vice versa. For example:
-
-    1. Ordered item 1
-    2. Ordered item 2
-
-    * Unordered item 1
-    * Unordered item 2
-
-will result in the following output:
-
-    <ol>
-      <li>Ordered item 1</li>
-      <li>Ordered item 2</li>
-    </ol>
-
-    <ul>
-      <li>Unordered item 1</li>
-      <li>Unordered item 2</li>
-    </ul>
-
-Whereas the default Markdown behavior would be to generate an unordered list.
-
-Note that, unlike the default Markdown behavior, if a blank line is not
-included between list items, the different list type is ignored completely. 
-This corresponds to the behavior of paragraphs. For example:
-
-    A Paragraph.
-    * Not a list item.
-
-    1. Ordered list item.
-    * Not a separate list item.
-
-With this extension the above will result in the following output:
-
-    <p>A Paragraph.
-    * Not a list item.</p>
-
-    <ol>
-      <li>Ordered list item.
-      * Not a separate list item.</li>
-    </ol>
-
-In all other ways, Sane Lists should behave as normal Markdown lists.
-
-Usage
------
-
-From the Python interpreter:
-
-    >>> html = markdown.markdown(text, ['sane_lists'])
-
-To use with other extensions, just add them to the list, like this:
-
-    >>> html = markdown.markdown(text, ['def_list', 'sane_lists'])
-
-The extension can also be called from the command line using Markdown's `-x` 
-parameter:
-
-    python -m markdown -x sane_lists source.txt > output.html
