Added filtering options to dining menu view

There is now a filter button by the search bar in the menu view for locations! This opens a menu that allows you to filter by diets and to filter out any allergens that you need to avoid. These options are all written to UserDefaults, allowing you to set your options once and have them persist across menus and sessions.
Also started on some refactors, these will be furthered in a later commit.
