reverted some changes from rev 521, because problem was in SegmentControl initialization, that happened in class constructor. It should not happen due to possible race-conditions, and, even more definitely, should not happen before plugin initialization (constructor+configure). Related to Issue [DSB-586]
Set the format of Xlocal for CPT's & borings linked to SoilSegments. Note; i had to move initialization of DSoilModelContext to make this work. Related to Issue [DSB-586]
