Remove return bool tests

As the compiler does not implement functions yet, the return statement is
effectivly the exit code of the implicit main functions. As OS'es usually
allow only positive natural numbers as exit codes, only returning longs
is specified and implemented yet. Therefore the returnBool tests have been
removed.
