Make some Animal methods pure virtual

There already were some pure virtual methods so the task was fulfilled
in ex01 already. It maybe should not have been.

For the evaluator of ex01: The Animal may not be abstract by removing
the pure virtual methods. The methods then have to be called from main
through dynamic_casting the Animal pointers to the Derived pointer
types, which have the methods defined.
