Enforced integer constraint when adding a new student user (for is_disabled and is_active).

Fixed bug in advise.module which was preventing alphabetic CWIDs from working.

Changed cumulative_hours in students table (as well as a couple other fields) to be
varchar(20) instead of varchar(5). This is because at only 5 characters, students
with 123.45 hours were violating the constraint on the table, and causing routines
to die.
