New: *Simple Diff Scanner* (closes #22).

* Highlights unified diffs, especially like the ones svn diff outputs.
* Changes to make highlighting of whole lines were necessary.
* I added two example files.

More changes:
* Added token classes :head, :delete, :insert, and :change along with styles.
* Added two new special token types: :begin_line and :end_line. They mark token groups that explicitly span whole lines and should be highlighted as such.
* The HTML encoder converts these new tokens to DIVs. May need more work.
* The Debug Encoder uses square brackets for line tokens.
* Some cleanups.
