Allows SmartyPants to be used independently from Markdown, to solve incompatibility with other SmartyPants modules  when users do not want Markdown.

updating markdown and smartypants ports to circumvent PHP 5.1 problems (http://drupal.org/node/54121)

by the coding standards, see CODING_STANDARDS.html). I also unified the
format and the location of the $Id$ tag. It starts with "//" and is placed
on the second line in all *.module files, now.

forgot about that base href -- nameref links now using non-clear-URL syntax, i.e. ?q=markdown/#anchor

The Markdown with SmartyPants module allows you to enter content using Markdown, a simple, plain text syntax that is filtered into valid XHTML, and will automatically convert plain ASCII characters to their proper Unicode entities in context ("curly quotes," et al.) using SmartyPants.
