Support programatically registered commands

[dzikoysk]

Hey, could you provide a possibility to register multiple command executors/support programmatically registered commands through the Console API? ❤️

At this moment we can only use one command executor per instance. It works for some simple utilities, but it's not enough for a greater projects with a bunch of commands and component based layout. You can just collect their instances by e.g. addCommandExecutor instead of setCommandExecutor, it would be very helpful :)

That sounds useful! If you have the time, you can submit a pull request yourself, otherwise I will try to get to it soon.

Unfortunately I don't have enough time to develop this project :(
