Add :disable_parsers option.

[agriffis]

I'm using kramdown with jekyll, and I'd like to defer smart quotes and typographic dashes to rubypants via jekyll-pants. However kramdown makes this hard/impossible because there's no way to disable the built-in parsers.

(There is a workaround for smart quotes, which is to set smart_quotes: apos,apos,quot,quot, but this is clearly a hack and doesn't help for dashes and ellipses.)

This pull request adds :disable_parsers so that one could set disable_parsers: typographic_syms,smart_quotes to properly defer that processing. I made it generic rather than specific to those parsers since it seems like it could be generally useful.

This won't be merged since the kramdown parser is not a only-take-what-you-like parser, it is designed to parse all documents created for it and therefore isn't customizable.

If you don't like how the kramdown parser works and/or if you need to add or remove a certain parser, you can create a new parser based on the kramdown parser. See the Markdown parser for an example.

@gettalong Thanks for the hint! I ended up with a simple subclass, see https://github.com/scampersand/jekyll-pants/blob/master/lib/jekyll/pants/down.rb and instructions for using it with jekyll at https://github.com/scampersand/jekyll-pants#compatibility-with-kramdown

A way to disable Typographic Symbols would be nice since there are user like me, who prefer ascii over typographic symbols. And it's a bit annoying to replace them back to ascii.

@fliiiix Understanding that you're probably looking for a command-line option or something... Nonetheless, the small subclass I provided at the link above does exactly what you're looking for.
