Add an alternate bootstrap method, next to the current one.

This bootstrap method first renders as plain HTML, and when JavaScript/AJAX is available, upgrades to the AJAX version.

This address a number of issues/annoyances/improvements:

• Support for google ads, and other things that are needed within the HTML page at load time
• Requires only 1 round trip to render the page (even if only after the second request AJAX functionality becomes available)
• Avoid IE problems with loading stylesheets dynamically

The implementation would require that:

• createAppliation() will have a WEnvironment that indicates no support for JavaScript or AJAX
• We add a virtual void WWidget::enableJavaScript() method which allows a widget to react to the fact that AJAX is available
• The built-in widgets need to react properly, including taking into account DomElement wrapped buttons.
