Kattis UI Fix by Ahmed Siadomar

Kattis recently overhauled their UI, and in the new wave of changes two very important buttons were unfortunately removed: the "My Submissions" and "Statistics" buttons on each problem's page. But no more! With this extension, these buttons will come back better than ever! You will be able to finally feel more familiar with the new Kattis design, as we all know that UI overhauls can be difficult and trying times.

Additionally, this extension adds a "Toggle Editor" button to toggle viewing/hiding the new code editor panel. Now you can view the problem description in it's full form (which hopefully results in more AC and less WA).
