Command.toString: include id for debugging;
Command.consume: explicit forward, avoid dependency on Session and side-effect on event bus;
State.+ without side-effect on event bus;
Session.commands_changed: delayed command changes (outside of Swing thread), also subsumes former Session.results;
Document_View: tuned commands_changed handling and caret listening;
Document_View.selected_command: proper function, not event handler state;
Output_Dockable: directly act upon commands_changed, not caret events (via former Session.results);
