Brightspace Grasple Layout wot Johnylilmoney

grasple in brightspace is unusable unless you're on a 1080p screen that is horizontally mounted. This extension was to fix it, but I wanted to have it on firefox as well instead of just chrome.
It's supposed to just be css/js canges, this version stores the divider locations so you don't gotta move em every time if you have a preferred position
