Add coloring support for the summary. This should make it
easier to read when you are using a color capable browser.

This will not impact a text-only browser.

Changes include:

o Code cleanup
o Add CSS style's.
o Use the new CSS style's.
o Move double quotes to quotes where needed.
o Made the HTML (except for the header) html-compliant.

The usage of CSS makes it easy to merge later when/if needed.
