Added sql query to delete from the database all the repeated theoretical classes. A theoretical class is considered repeated when there's more than one record with the same 'day', 'duration', 'start_time', 'composed_class_name' and 'course_unit_id' fields.
A script to test this issue will be done later together with issue #31.
Closes #34
