Side by side view for labs

[raph-amiard]

Coming from feedback using the labs in EPITA for Ada classes:

It would be great to have a side by side view for the labs, where you have the assignment, and the code editor to the right (or vice versa).

The point is that at the moment, when the assignment is a bit long, you have to scroll back and forth to read the requirements, where most screens have more than enough space to accomodate side by side view.
