Update to #722, not yet ready to merge.

Completed:

• Padding is added to the bottom of the results page (see images 1 and 2).
• Buttons are clickable no matter where your cursor lies.
• Scrolling is functional on mobile screen sizes and large browser layouts.

To finish next time:

• Scrolling in odd browser sizes (it is currently omitted some results as well as the pagination).
• Updating the URL as the user types in the search bar.

Update to #722, ready for review.

Completed:

• The policy and pagination content-box are now scrollable for smaller screen sizes (Image 1). This change is also applicable on mobile.

• Policies with large titles now wrap when necessary, both when finding a policy and selecting one (Image 2).

• The URL bar now mimics the search bar. The search bar also mimics the URL when it contains a specific endpoint. (Image 3)
