HUGE Update

This update changes so many things it’s hard to count them:

Changed highlighting links so that they didn’t look so ugly
Added a Favicon (logo for the website that shows up in the tab)
Added Recipes and MyRecipes pages
Updated background files such as models and controllers so that they
would fit the Recipe -> Ingredient model (I can explain this better
next class)
Fixed the Nutrition pages so that the accordions close when another is
opened, spacing is also better
Added a profile page for users where they can also access the recipes
they have created, this page may not be necessary though when we can
just use the “My Recipes” page that already exists.
