Bug 928254 - [Flatfish][Gallery] support 2 column layout for tablet
1. remove doms depends on device layout, so we don't use -tablet elements anymore, 2. remove HasFocusdOnThumbnail, instead, we use currentFrame.displayingImage to filter, 3. lazy load frames_script.js before switching view, 4. resize the frames when orientation change and currentView is in thumbnailListView condition
