Feature Sprucing

Features were either added or refined to create a really great
experience
-Better photo sharing: captions now work thanks to a simple hack, and
sharing to the app works better too. Additionally, it will do error
handling
-One menu icon can launch the camera or gallery
-You can repick a photo by clicking on it in the Upload UI
-Renovated upload UI that looks much cleaner and focused on the photo
-Experimental camera code was created, but it is still very buggy and
looks unattractive
-General bug fixes
