Codecademy Redesigned

This extension combines several previous extensions and completely revolutionizes your experience on Codecademy.

- Adds a new Canned Responses feature into the forums for people who type the same thing a lot
- Redesigns the Forums to have darker colors with more contrast, to strain the eye less
- Adds a link in the footer to a GitHub repository containing old posts saved from Groups, including many useful tutorials.
- Makes the notification bell link to your [Discuss][1] notifications, instead of the old notifications page
- Updates the Profile Page, adding 'points today', 'best points day', and best day streak' back into the profile.

Enjoy the improvements, we plan on adding many more :)
