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.

-Markdown documents.
-
-This extension is included in the standard Markdown library.
-

-
-Definition lists are defined using the syntax established in 
-[PHP Markdown Extra][php].
-
-[php]: http://www.michelf.com/projects/php-markdown/extra/#def-list
-
-Thus, the following text (taken from the above referenced PHP documentation):

-    :   Pomaceous fruit of plants of the genus Malus in 
-        the family Rosaceae.

-
-    <dl>
-    <dt>Apple</dt>
-    <dd>Pomaceous fruit of plants of the genus Malus in 
-    the family Rosaceae.</dd>
-
-    <dt>Orange</dt>
-    <dd>The fruit of an evergreen tree of the genus Citrus.</dd>
-    </dl>
-
-
-Usage
------
-
-From the Python interpreter:
-
-    >>> html = markdown.markdown(text, ['def_list'])
-
-To use with other extensions, just add them to the list, like this:
-
-    >>> html = markdown.markdown(text, ['def_list', 'footnotes'])
-
-The extension can also be called from the command line using Markdown's `-x` 
-parameter:
