Hide component action commands from parent device

[apwelsh]

The LZW31 (for example) has buttons that are non-functional in the GUI as they pertain to the component child devices. Please remove the commands for the component child devices from the device metadata definition.

Ex:

        command "componentOn"
        command "componentOff"
        command "componentSetLevel"
        command "componentRefresh"
        command "componentSetColor"

these commands should be removed from the definition section to clean up the clutter and because the are non-functional in the web interface.
