ferret7 -script .... returns to Python prompt when error occurs

When a script is run using "ferret7 -script myscript.jnl" to start pyferret, if myscript.jnl contains an error, it exits to the python prompt instead of exiting completely.

This is due to the problem raising an exception that returns control back to Python before completing the semicolon-separated list of commands which ends with a Ferret "exit". (And because of the python call in the ferret7 shell script includes "-i", the exception doesn't exit python.)
