Make sure all command functions return True

Because recent adjustments to handler_active() rely on the
call_handler_function() return value to determine whether something
went wrong, we need command functions to return something which
evaluates boolean True if they ran to completion and didn't raise an
exception. Just return True from all of them for now, but they may
see more dynamic result handling in the future.
