Add basic support for Web Applications
Allow to save any page as a "Web Application". A new .desktop file will be created, and added to the Shell as a new application. It will launch epiphany in application mode, with its own private profile (inheriting some data from the main profile, like the relevant domain cookies) and in a new process.
