BIM model import

In certain applications included in the Open BIM workflow, in the panel where the files to be imported from the BIM project are selected, it is also possible to select whether the programs that have generated those files are of the "Initiator" or "Additional" type. In the 2019.b version, the name of these types and the texts of the headings of the table where the selection was carried out were not correct. The names and texts of the headings are corrected in the 2019.c version.
