other new features

- check for updates when app launches
- remove scrollview so that recyclerview can recycle. It wont hide the top bar but thats a sacrifice for the greater good.
- remove download all mini card and made it into a floating action button
- made video loading from playlists as fast as possible even if you have thousands of videos in a list. It adds videos in recyclerview in a form of pagination
- fixed preferences when you just installed the app and you never opened the preference screen you can still download without erroring out
