Admin console: standalone server doesn't require distinct socket binding groups

see screenshot. In standalone mode, a standalone server does not support defining multiple socket binding groups, there can be only one, by default it is named 'standard-sockets' (at least I understand it this way, it is specified in jboss-as-config_1.1 xml schema). Therefore the checkbox for picking one of socket binding groups is irrelevant, because it cannot provide any choices.

By the way, it could be useful to have the possibility to change the name 'standard-sockets' using admin console.
