Hide or disable the Change Password option when appropriate

Previously, the Change Password option would be shown all the
time, even the the client was connected to a core not supporting
the password change functionality or if a monolithic build was in
use.  Now, the Change Password option will be disabled if the
client is disconnected or is connected to a core not supporting the
functionality and will be hidden if a monolithic build is in use.
