Adding more markdown files to generated documentation

[0gust1]

Possibly related to #78

Actually, if there is a readme.md file, styledocco process it and use it as the index page of the generated documentation.

It would be nice to have the possibility to add other markdown files (for exemple project technical documentation not directly related to CSS/LESS/SASS), to be included in the generated documentation. However, this can be achieved by numerous other ways.

What do you think about that ?

Sounds useful. I can see it going the other way as well, integrating Styledocco into existing documentation. If you could output the docs minus the chrome, then it would be trivial to put it into any website. This would probably be covered by the custom template work.
