Request to merge software engineering lab result to master

- New UI with twitter bootstrap
- Support for makefile based C exercises
- Submissions can be made public and then viewed by others if all tests have not passed
- Fixed a bunch of broken integration tests due to the new UI
- Latest submission can now be downloaded, and the link to this submission can be found in the courses.json

It was lots of fun :)
