Factored out the building of the various processors and patterns into utility functions called by a build_parser method on the Markdown class. Editing of the processors and patterns now all happen in one file for each type. Additionaly, a subclass of Markdown could potentially override the build_parser method and build a parser for a completely differant markup language without first building the default and then overriding it.
