EMSL Baguette Server, Util, Baguette Client Install: Extended BaguetteServer to generate a new, random username/password pair on startup. This pair is preferred over the provided credentials in configuration file. Modified CredentialsMap in order to store preferred pair. Modified VmInstallationHelper to select the preferred pair (if any) when generating baguette client configuration data. Added 'PasswordUtil.getDefaultPasswordEncoder()' static method, used in CredentialsMap. Few minor code improvements
