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

bugfixing for UL. Remaining problems: CCE allocations in subframe 5 lead to occasional illegal DCI allocations (affects UL DCI which is missed by UE). waveform compliance with CQI in ULSCH.

added Timing advance tracing to .vcd output. Increase maximum UL RB count to 45. Measured UL throughput @ 15 Mbit/s (40 PRBs).

changes in BSR handling in eNodeB. UL throughput on 5 MHz is 8 Mbit/s (mcs 19, 20 PRB). MCS 20 is not working for an unknown reason.
