User has to manually set magic_vpsc_box_path

Per our discussion of this issue, will implement a config file that sets default locations for the magic VPSC box on the first time that startup_api() is run, and customize a setter function for run.magic_vpsc_box_path so that it can be flagged to either permanetly update the config, or to be set differently only for a single run.
