Please review the attached patch (revised) which implements alternative CLI password methods to address the following PKI TRAC ticket:

• PKI TRAC Ticket #555 - Other ways to specify CLI password

This revised patch attempts to address most of the comments to the previous patch including:

• made numerous man page changes
• camelCased method names
  
• changed the password routine to utilize the '=' delimiter rather than the ':' delimiter (more appropriate for Java)
  
• consolidated the two password file routines into a single routine which supports 'token=password' format (as well as documenting and providing man page examples for how to utilize this style of file with a simple password)
• removed all warning messages from the password routine
  
• utilized suggestions to improve the password routine including replacing the use of the StringUtils.split() method with the String.split() method using a regex
• rewrote password routine to handle passwords that contained the delimiter as a part of the password
  
• ditched 'DRM'
  
• removed consolidated error messages and exited immediately
  
• removed the '-y' option
  
• moved password prompting under the control of the pki CLI program for both basic and client authentication
  
• removed previous changes to URI/URL
  
• removed previous changes to subsystem type
• added mutual exclusive test for "-n" (client authentication) vs. "-u" (basic authentication) options
• added mutual dependency tests as needed
