edit script on course views

the courses views are now functional! and they look nice. 
three important things to left to do: 
- find a better way to load course content (it doesnt work now) and 
- restructuring of the files & folders (maybe we can discuss this?)
- design smaller logo
Sling, you can push/pull to the main server now 

feel free to test things & if something doesn't work or I messed something somewhere you can open issues!
