Create swipeableDrawer component

- CommentsList needs to return a title with comment amounts
- mobile player dimensions needed to fill in the cover
- hid livestream header for now until figuring out a better presentation
- ~colum-reverse~ was causing problems with MUI's drawer scrolling, so reversed the chat order and made it ~column~ by default
- Hid bottom expand navigation if component not yet opened
- some other style changes in the middle
