Import Tool: Save <Job Name> per Session, not global

Import-Tool, Naming-section "Job Name" suggested as used during last import, even when that was used in a different session. Since I use token <Job Name> for import-file naming, I often get wrong filenames when adding additional images to an already existing session, because I sometime forget to re-adjust the Job Name. Please save the "Job Name" within the current session-context, like you seem to do with the digit-counter.
