Convert / in coursename to -

Some Connect course names has a / in the subject and course code section.
E.g.:
MATH101/103

It indicates that both Math101 and Math103 uses this course. Course name
sanitization strips out the /. This was changed so that the / is converted to -
instead.
Convert course name convenience script.

This script basically uses the same code path that is used during LTI import to
convert Connect course names into Webwork compatible course names. It's a
convenience script that tells us what the resulting name would be without
having to run the conversion. To use it, just call the script with the Connect
course name as a parameter.
