Commands do not implement PluginIdentifiableCommand

[SOF3]

This prevents Poggit from detecting the command, and hence the plugin cannot be searched at https://poggit.pmmp.io/cmds

This issue has been reported to Commando at CortexPE/Commando#26, but before @CortexPE fixes it (which is most likely impossible without a BC break), it is the responsibility of plugins to make sure they implement this interface.
