Still a WIP 

* Right now, clicking on the "Subscribe" buttons has no effect. This will come in a future PR
* I cleaned the CSS by removing dead CSS classes
* I deleted static.css and merged the CSS of that file in a CssResource (see style.css), so one less round-trip to the server to get CSS! Also, style.css is now a NotStrict CssResource.
* I used ArcBees Mail for sending emails (instead of using project-specific classes)
