Hi MOD developpers!

I've added some commands to mod-host that can be useful for getting more feedback from the server about the running effects, its presets and parameters. I've not added tests, but if you finally push the new commands into the main, i could add it.

Also, if you think that other command names would fit better, tell me, or change it directly ;-)

Kind Regards!
