You could probably copy and paste the entire common.js to your common.js, but you would have to change the links like 'MediaWiki:Common.css/calc.css' to 'u:runescape:Common.css/calc.css'. To do that, you can press Ctrl + H in the code editor to find and replace iterations of 'MediaWiki' to 'u:runescape'.
