This is a first step to stop using "unsafe" web sections.

This updates support request app to not require script-src: unsafe-eval and style-src: unsafe-inline in the CSP. Dropping script-src: unsafe-eval is made possible by using domsugar instead of handlebars for dynamic content. Dropping style-src: unsafe-inline by using CSS files instead of inline style attributes in the DOM. One minor regression is that the tooltips from the graph on the front page gadget will cause warning because of unsafe-inline and not render the series color.

This application was also modernized a bit, it now uses the HTML viewer gadget to display post contents and supports translation.
