Markdown Shortcode

Damn simple [markdown]#via shortcode[/markdown] for wordpress.
This plugin uses parsedown and highlight.js. Zero configuration.

Write this into the editor:

[markdown] #h1 

h2

text ____source code (two ore more underscores will be replaced by empty spaces) ____source code (two ore more underscores will be replaced by empty spaces) `javascript source code ` [/markdown] 

and the shortcode content will be parsed with parsedown. Syntax highlighting will appear for the source codes.

This plugin is available at github, too.
Please report issues at github, pull requests are welcome, too!
