Bonsai - set active bsdd when loading project

When loading an ifc project it will search it for bsdd ifcclassifications and will set one as active if finds it, so now it will be a bit more convenient working with bsdd classification assignment as it active bsdd previously was always getting reset when you reload ifc file.
