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.

-WikiLinks
-=========
-
-Summary
--------
-
-An extension to Python-Markdown that adds [WikiLinks][]. Specifically, any 
-``[[bracketed]]`` word is converted to a link.
-
-[WikiLinks]: http://en.wikipedia.org/wiki/Wikilink
-
-This extension has been included in the Markdown library since 2.0.
-
-Syntax
-------
-
-A ``[[bracketed]]`` word is any combination of  upper or lower case letters,
-number, dashes, underscores and spaces surrounded by double brackets. Therefore 
-
-    [[Bracketed]]
-
-Would produce the following html:
-
-    <a href="/Bracketed/" class="wikilink">Bracketed</a>
-
-Note that wikilinks are automatically assigned `class="wikilink"` making it 
-easy to style wikilinks differently from other links on a page if one so 
-desires. See below for ways to alter the class.
-
-You should also note that when a space is used, the space is converted to an
-underscore in the link but left as-is in the label. Perhaps an example 
-would illustrate this best:
-
-    [[Wiki Link]]
-
-Becomes
-
-    <a href="/Wiki_Link/" class="wikilink">Wiki Link</a>
-
-Usage
------
-
-From the Python interpreter:
-
-    >>> text = "Some text with a [[WikiLink]]."
-    >>> html = markdown.markdown(text, ['wikilink'])
-
-The default behavior is to point each link to the document root of the current 
-domain and close with a trailing slash. Additionally, each link is assigned to 
-the html class `wikilink`. This may not always be desirable. Therefore, one can
-customize that behavior within Python code. Three settings are provided to 
-change the default behavior:
-
-1. **base_url**: String to append to beginning of URL. 
-
-    Default: `'/'`
-
-2. **end_url**: String to append to end of URL.
-
-    Default: `'/'`
-
-3. **html_class**: CSS hook. Leave blank for none.
-
-    Default: `'wikilink'`
-
-4. **build_url**: Callable which formats the URL from it's parts.
-
-For an example, let us suppose links should always point to the subdirectory 
-`/wiki/` and end with `.html`
-
-    >>> html = markdown.markdown(text, 
-    ...     ['wikilink(base_url=/wiki/,end_url=.html)']
-    ... )
-
-The above would result in the following link for `[[WikiLink]]`.
-
-    <a href="/wiki/WikiLink.html" class="wikilink">WikiLink</a>
-
-If you want to do more that just alter the base and/or end of the URL, you 
-could also pass in a callable which must accept three arguments (``label``, 
-``base``, and ``end``). The callable must return the URL in it's entirety.
-
-    def my_url_builder(label, base, end):
-        # do stuff
-        return url
-
-    md = markdown.Markdown(
-            extensions=['wikilinks],
-            extension_configs={'wikilinks' : [('build_url', my_url_builder)]}
-    )
-
-
-The option is also provided to change or remove the class attribute.
-
-    >>> html = markdown.markdown(text, 
-    ...     ['wikilink(base_url=myclass)']
-    ... )
-
-Would cause all wikilinks to be assigned to the class `myclass`.
-
-    <a href="/WikiLink/" class="myclass">WikiLink</a>
-
-The same options can be used on the command line as well:
-
-    python markdown.py -x wikilink(base_url=http://example.com/,end_url=.html,html_class=foo) src.txt
-
-Some may prefer the more complex format when calling the `Markdown` class directly:
-
-    >>> md = markdown.Markdown( 
-    ...     extensions = ['wikilink'], 
-    ...     extension_configs = {'wikilink': [
-    ...                                 ('base_url', 'http://example.com/'), 
-    ...                                 ('end_url', '.html'),
-    ...                                 ('html_class', '') ]},
-    ...     safe_mode = True
-    ... )
-    >>> html = md.convert(text)
-
-Using with Meta-Data
---------------------
-
-The WikiLink 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:
-
-* `wiki_base_url`
-* `wiki_end_url`
-* `wiki_html_class`
-
-When used, the meta-data will override the settings provided through the  
-`extension_configs` interface. 
-
-This document:
-
-    wiki_base_url: http://example.com/
-    wiki_end_url:  .html
-    wiki_html_class: 
-
-    A [[WikiLink]] in the first paragraph.
-
-would result in the following output (notice the blank `wiki_html_class`):
-
-    <p>A <a href="http://example.com/WikiLink.html">WikiLink</a> in the first paragraph.</p>
