escape forward slash

Quick fix for FP#573743 - Architecture BA (Hons) - ARB/RIBA Part 1 has a '/' in the name

This really needs to be refactored during our tidy up sprints

Issues:
- logic in view
- only certain special chars accounted for (e.g. if course has backslash it will break again)
- better solution would be some regex to ignore everything that isn't a letter or number
