Site Upgrades

A brief note - I'm making significant revisions to the site, including the introduction of Hemi, the third major revision to Engine for Web Applications.

I cleaned up the site templates (A MasterPage, some static skeletons for HTTP Handlers, and XSL for the static documents) to remove extraneous HTML and tweak the navigation. In particular, session and login related items were pushed to the right, adjacent to the framework developer tool. I also cleaned up the CSS and reduced the amount of startup scripting used to instrument the Engine Gizmos, primarily by using better use of CSS as well as new features in Hemi.
