Cleanup: make DiveImportedModel::checkStates a std::vector

Browse source 
To not have to bother with memory-management. Moreover, the
old code was in principle wrong, since it assumed that
sizeof(bool) == 1. Of course, this is true for all supported
platforms, but let's not depend on such implementation-defined
behavior anyway.
