* A bunch of refactors in public JS files (home.js, dashboard.js, etcetera). * Added lazyload to home page (for thumbs of uploaded images), dashboard (for thumbs view) and albums' public link. Albums' public link will silently fallback to loading all thumbs at once if JavaScript is disabled. * A bunch of others code improvements. Honestly I'm too lazy to track all the changes.
