Sidebar progress
Updated Sidebar to give users a better experience.
Changed button colours and interactivity to match web-app design
Updated meal information to show users in a better style.  I feel this emphasizes the uniqueness of each person.  Before it was more of a list format, and made people fall into categories, now it looks like a user profile, without structure.
Fixed the join meal marking not changing into selected marker. Also created a method that checks to see if user is allowed to join meal. Currently set to hard limit of 1.
