Add feature for custom sorting of My Courses

[Jeremy Hopkins]

This feature is required by Coventry University. It allows one or more profile fields to be specified to generate a list of current courses. These courses will be shown as expanded in the course list, others will be shown collapsed under "Other Courses". This provides a mechanism to keep navigation current for students from one years study to the next.
