Start refactoring getAll.py to remove usage of split and manual parsing in favor of BeautifulSoup's built-ins.

Have refactored GetTerms, GetColleges, and GetSubjects, still need to do
GetClasses. Somehow, the output is now backwards (starting with WBDV and working down
to ANIM). Further work is necessary to remedy this problem, and to
finish refactoring GetClasses.
