Added paper view

[Slartibartfass2]

Closes #34

What I have made

• the root layout file has now a container with the style that is used in every page of our application
• added a reusable tooltip component
• added some aria labels to existing components for improved accessibility
• added paper view, consisting of the following components
  • bookmark button (logic is implemented in [Use Case]: Add Paper To Reading List #99 and [Use Case]: Remove Paper From Reading List #100)
  • navigation button = previous/next paper button (due to the tooltip being unable to be an a tag when providing a href prop (like a button would do), this button uses goto to navigate to the previous/next paper)
  • paper cards are the two card components on the paper view, which display paper information
  • the content of these cards will be implemented in other issues, this also includes the testing for these cards, testing it now wouldn't make sense
  • decision buttons to either accept, decline or mark a paper as undecided (maybe button)
    • there is a component for each decision, which seems a lot, but providing different styles depending on a type/state prop was less readable
• added a setup test file to mock the goto method used in the navigation buttons
• the paper view component is shown on the project dependent and independent pages
• this PR adds the general structure and the views will be extended in future issues, I wouldn't add more to it now

Great work! There were some things though that stood out to me. Looking forward to hearing your thoughts on these points.

[Slartibartfass2]

Thanks for the review, I'll rebase when we're finished so that you see the changes I made.
