setup and exiting

[Max Bowsher]

Here is a list of places where setup exits not-by-LogSingleton.

NB: I haven't checked for potential uncaught exceptions, which might give
other ways to exit not-by-LogSingleton.

PickView.cc:414:    exit (10);
PickView.cc:425:    exit (11);
String++.cc:79:     exit (100);
String++.cc:93:     exit (100);
String++.cc:201:    exit (100);
String++.cc:215:    exit (100);
msg.cc:46:          ExitProcess (0);
package_db.cc:122:  exit (1);
