Result of testing as eNodeB. modifications for .vcd logging, bugfix in eNB_thread_FH (subframe counter), update of .conf file for new threading parameters. Updates to gtkwave configuration file for new threading.

set transmission mode in phy_config_dedicated_[UE|eNB] after RRCConnectionReconfiguration(eNB) and RRCConnectionReconfigurationComplete(UE)

add ue_TransmissionMode in RrcConfigurationReq

added ue_transmission_mode and nb_antenna_ports to eNB config file

transmisison mode gets set with RRCReconfiguration
