Replace first semester links with 2nd semester links

[kittsville]

The 2nd semester has begun so all the current links need replacing with links relevant to this semester's 4 Comp Sci courses:

• CS3518: Languages and Computability
• CS3524: Distributed Systems and Security
• CS3525: Enterprise Computing and Business
• CS3528: Software Engineering and Professional Practice

[kittsville]

It's probably worth keeping the link to the CS3028 discussion board as it may still be in use, awaiting confirmation at the Tuesday meeting.

I'll leave this issue open until assessment deadlines have been confirmed and all courses have been released on MyAberdeen.

CS3524 isn't Adaptive Interactive systems it's Distributed Systems and Security. I think there's an error of MyAberdeen.

The homepage being linked needs updating.
