v1.1 Corsego MVP - bug fixes, stability

Fixed multiple bugs and errors.

v1.0 Corsego MVP

After 214 commits and a few months of hard work I'm proud to say that the first stable version of Corsego is released.
Core features:

• Admin can manage user roles (admin, teacher, student) and moderate courses
• Teachers can create feature-rich courses with lectures and track different metrics
• Students can pay for courses via Stripe and view course content
• Teacher and student balance is updated based on course enrollments, but all the money goes to the single master Stripe account.
