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.

-Abbreviations
-=============
-
-Summary
--------
-
-The Markdown Abbreviation Extension adds the ability to define abbreviations. 
-Specifically, any defined abbreviation is wrapped in  an `<abbr>` tag.
-
-The Abbreviation extension is included in the standard Markdown library.
-
-Syntax
-------
-
-Abbreviations are defined using the syntax established in 
-[PHP Markdown Extra][php].
-
-[php]: http://www.michelf.com/projects/php-markdown/extra/#abbr
-
-Thus, the following text (taken from the above referenced PHP documentation):
-
-    The HTML specification 
-    is maintained by the W3C.
-        
-    *[HTML]: Hyper Text Markup Language
-    *[W3C]:  World Wide Web Consortium
-
-will be rendered like so:
-
-    <p>The <abbr title="Hyper Text Markup Language">HTML</abbr> specification 
-    is maintained by the <abbr title="World Wide Web Consortium">W3C</abbr>.</p>
-
-Usage
------
-
-From the Python interpreter:
-
-    >>> import markdown
-    >>> text = """
-    ... Some text with an ABBR.
-    ...
-    ... *[ABBR]: Abbreviation
-    ... """
-    >>> html = markdown.markdown(text, ['abbr'])
-
-To use with other extensions, just add them to the list, like this:
-
-    >>> html = markdown.markdown(text, ['abbr', 'footnotes'])
-
-Abbreviations can also be called from the command line using Markdown's `-x` 
-parameter, like so:
-
-    markdown.py -x abbr source.txt > output.html
