Improvements on Totem edX theme ("About course" page)

Here are some small improvements on the page that make it a bit cleaner and more alike Totem landing. I came up with more obvious visual dividing of varied blocks so that content doesn't merge.

You can notice in the second screenshot that the title and course number are gone from header. This is what I'd like to do due to the fact that this info is also present on the page itself, but first I'll have to figure out if this element serves any specific functional purpose.
