Changeset 6233 for main/waeup.sirp/trunk/src/waeup/sirp/university

Message:

Replace old clear() implementation with a call to internal function
implemented in C. This way we not only get tremendous speedup for the
clear-action but also kick a faulty implementation. The old one
removed only half of the items contained and the test didn't check
that properly.
