sst-core does not initialize non-uniform links correctly

[jjwilke]

a single call to

top_->configure_port_params(0, switch_params)

in python_topology.cc. sstmacro.py really needs to get modified to configure ports. This interacts in a complicated way with

SSTIntegratedComponent::init_links(sprockit::sim_parameters *params)
