Subject: Re-implemented previews in homepage without using plugins. Not
 finished yet : Little things that change: -nice buttons appearing on hover
 -transitions on hover TODO: -when a preview is empty or when loading, it is
 very ugly -for now there's no way to choose the page you want to preview
 -port "closed Tabs" to this new architecture -totally remove PreviewImage
 classes -eventually, specific contextmenu for previews
