Becoming More Available

I have added:

• A service worker for offline support. As long as you have viewed the recipe once, it is saved on your device and you can view it any time, even without internet
• Page prefetching: If you hover over a page on desktop or its visible on your screen on mobile, your browser will start grabbing it automatically. If you actually click on it, it will load almost instantly
• Added the correct caching headers to ensure assets are saved with logical lifespans
• RSS Feeds are now auto discoverable
