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.

-HeaderId
-========
-
-Summary
--------
-
-An extension to Python-Markdown that automatically generates 'id' attributes
-for HTML header elements (h1-h6) in markdown's output.
-
-This extension is included in the standard Markdown library.
-
-Syntax
-------
-
-By default, all headers will automatically have unique "id" attributes 
-generated based upon the text of the header (See below to turn this off). 
-Note this example in which all three headers would have the same "id":
-
-    #Header
-    #Header
-    #Header
-
-Results in:
-
-    <h1 id="header">Header</h1>
-    <h1 id="header_1">Header</h1>
-    <h1 id="header_2">Header</h1>
-
-Configuring the Output
-----------------------
-
-The HeaderId extension has four configuration settings:
-
-* **level**: Base level for headers.
-
-    Default: `1`
-
-    The `level` setting allows you to automatically adjust the header levels to
-    fit within the hierarchy of your html templates. For example, suppose the 
-    markdown text for a page should not contain any headers higher than level 3
-    (`<h3>`). The following will accomplish that:
-
-        >>>  text = '''
-        ... #Some Header
-        ... ## Next Level'''
-        >>> html = markdown.markdown(text, extensions=['headerid(level=3)'])
-        >>> print html
-        <h3 id="some_header">Some Header</h3>
-        <h4 id="next_level">Next Level</h4>'
-
-* **forceid**: Force all headers to have an id.
-
-    Default: `True`
-
-    The `forceid` setting turns on or off the automatically generated ids for 
-    headers that do not have one explicitly defined (using the attr_list 
-    extension).
-
-        >>> text = '''
-        ... # Some Header
-        ... # Header with ID # { #foo }'''
-        >>> html = markdown.markdown(text, 
-                        extensions=['attr_list', 'headerid(forceid=False)'])
-        >>> print html
-        <h1>Some Header</h1>
-        <h1 id="foo">Header with ID</h1>
-
-* **separator**: Word separator. Character which replaces whitespace in id.
-
-    Default: `-`
-
-* **slugify**: Callable to generate anchors.
-
-    Default: `markdown.extensions.headerid.slugify`
-
-    If you would like to use a different algorithm to define the ids, you can
-    pass in a callable which takes two arguments:
-
-    * `value`: The string to slugify.
-    * `separator`: The Word Separator.
-
-Using with Meta-Data
---------------------
-
-The HeaderId Extension also supports the [Meta-Data](meta_data.html) Extension.
-Please see the documentation for that extension for specifics. The supported 
-meta-data keywords are:
-
-* `header_level`
-* `header_forceid`
-
-When used, the meta-data will override the settings provided through the  
-`extension_configs` interface. 
-
-This document:
-
-    header_level: 2
-    header_forceid: Off
-
-    # A Header
-
-
-Will result in the following output:
-
-    <h2>A Header</h2>
