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.

-Meta-Data
-=========
-
-Summary
--------
-
-An extension to Python-Markdown that adds a syntax for defining meta-data about
-a document. The Meta-Data extension is inspired by and follows the syntax of 
-[MultiMarkdown][]. Currently, this extension does not use the meta-data in any 
-way, but simply provides it as a `Meta` attribute of a markdown instance for 
-use by other extensions or directly by your python code.
-
-[MultiMarkdown]: http://fletcherpenney.net/MultiMarkdown_Syntax_Guide#metadata
-
-This extension has been a part of the Markdown library since 2.0.
-
-Syntax
-------
-
-Meta-data consists of a series of keywords and values defined at the beginning 
-of a markdown document like this:
-
-    Title:   My Document
-    Summary: A brief description of my document.
-    Authors: Waylan Limberg
-             John Doe
-    Date:    October 2, 2007
-    blank-value: 
-    base_url: http://example.com
-
-    This is the first paragraph of the document.
-
-The keywords are case-insensitive and may consist of letters, numbers, 
-underscores and dashes and must end with a colon. The values consist of 
-anything following the colon on the line and may even be blank. If a line is 
-indented 4 or more spaces, that line is assumed to be an additional line of the
-value for the previous keyword. A keyword may have as many lines as desired. 
-The first blank line ends all meta-data for the document. Therefore, the first 
-line of a document must not be blank. All meta-data is stripped from the 
-document prior to any further processing by markdown.
-
-Accessing the Meta-Data
------------------------
-
-The meta-data is made available as a python Dict in the `Meta` attribute of an 
-instance of the Markdown class. For example, using the above document:
-
-    >>> md = markdown.Markdown(extensions = ['meta'])
-    >>> html = md.convert(text)
-    >>> # Meta-data has been stripped from output
-    >>> print html
-    <p>This is the first paragraph of the document.</p>
-
-    >>> # View meta-data
-    >>> print md.Meta
-    {
-    'title' : ['My Document'],
-    'summary' : ['A brief description of my document.'],
-    'authors' : ['Waylan Limberg', 'John Doe'],
-    'date' : ['October 2, 2007'],
-    'blank-value' : [''],
-    'base_url' : ['http://example.com']
-    }
-
-Note that the keys are all lowercase and the values consist of a list of 
-strings where each item is one line for that key. This way, one could preserve 
-line breaks if desired. Or the items could be joined where appropriate. No 
-assumptions are made regarding the data. It is simply passed as found to the 
-`Meta` attribute.
-
-Perhaps the meta-data could be passed into a template system, or used by 
-various markdown extensions. The possibilities are left to the imagination of 
-the developer.
