Newlogy

Newlogy simplifies the Schoology Learning Management System interface, removing seldom-used components and modernizing styling.

Changes:
* Replace school logo with a simple "Home" link
* Remove "RECENT ACTIVITY" and "COURSE DASHBOARD" tabs
* Display course and group menus as a list again, not as a grid
* Use normal capitalization for header tabs to match rest of interface
* Disable school-colored links to match blue color scheme
* Replace blurry smiley faces next to like buttons with thumbs-up emoji
* Use consistent text coloring
* Conform better to new modern design language
* Add flag emoji next to language selection, just for fun
* Remove logged-in user's name from header
* Literally hundreds of other graphical tweaks
