No more System.exit(int)

It's nasty and hackish. Find a way to gracefully shutdown without relying on System.exit(). A good example of this is in Manager's constructor, which can not only exit the JVM, but starts threads (both undocumented).

Right, so this is more an issue of proper error handling. We currently System.exit(1) in two places:

$ grep -rin System.exit *
libbitster/Manager.java:87:      System.exit(1);
libbitster/Deputy.java:205:          System.exit(1);

Both are when we can't initialize something. They should put the appropriate object in an error state and probably write to the log.
