Migrated the code base to Visual Studio 2005 beta 2. Overhauled extensibility mechanism.

This allows for the development of new UI language modules without changing XUPClient source code.

Initial XUP idea was born. I was attending the W3C XMLP Working Group meeting at Novell's campus in San Jose, CA. I wasn't particularly interested in that day's discussion topics, so I spent sometime on the XForms draft instead. Unhappy with the fact that XForms maintained the form submission / page response paradigm, I started to work on a more fluid UI and application model for the web. The result was the birth of XUP.
