New: *JavaScript Scanner* (closes #23).

* It's quite good and fast, but still a beta.
* I included Prototype and script.aculo.us as example code for testing.

More changes:
* Added two new token classes, :keyword and :key, along with CSS styles.
** Actually, we should use :keyword for most scanners that now use :reserved.
* HTML Encoder: The CSS parser understands multiple selectors separated by commas.
