Support CSS templates

[coderarity]

We could add support for compiling Sass/LESS/Stylus templates to CSS. I think that they share a lot of similarities with HTML templates, with the important exception that they don't really have data binding. I guess that means you wouldn't pass anything into the render function.

So it'd look something like this:

var viewful = require('viewful');

var view = new viewful.View({ 
  template: "color: #FFFFFF",
  input: "less"
});

view.render();

I'll support any templating / markup language available.

Just start a fork and add the engine / tests.

Markdown would be a good one to start with.
