This commit fixes the following: 1. Unintented scrollbar was being created on the .modal container element 2. 15px gap between the footer and scrollable content, creating an odd visual lapse 3. Modal was too wide between 768px and 900px, bleeding off the page.
We need to extract any sprite-sheet css in this directory (anything that's not habitrpg-web specific) and move it to common
