Support UC_* specified in TFM_* tables

Note that parameters starting with UC can be defined also in any TFM_* tables. The Column for specifying the UC_N in TFM_* tables is UC_N. As always, the scenario order in the run case will determine, which value will survive (when the same instance of a parameter is defined in several scenarios), But I am not sure what will happen if the same parameter is defined in several tables in the same scenario (e.g. both ~UCT and TFM_* in the same scenario), haven't tested that.
