UI changes suggested by design subteam

These are some of the UI changes suggested by the design subteam.

Changes include:
- Image link opens in new tab (we can look into a better method later, but a new tab works fine for now).
- Voting and allergy icons are removed
- Wasted space between menus is removed
- Disclaimer is collapsible
- Buttons are changed to be smaller and fit on one line
