Bug 1048927 - Enable 'add to home' for all web content. r=vingtetun

This enables the 'add to home' option for all web content and not just
e.me results.
searchName is the title given back by e.me, which tends to match the start of the page title - this is a nasty hack, but then the whole thing is kind of a nasty hack... I'm not happy about this, but I'm also not sure what a good alternative would be that isn't too involved. If we didn't need to differentiate between e.me searches and sites, this would be unnecessary... I might ping UX about this.
