feedback: deleting a button that is an extra or sub command

[cybin]

If you have multiple bindings on a button, its likely that they each have different activation types. When you try to delete, 1) first you need to remove the command, then 2) reset activation, then 3) delete the command.
1) I don't know of a reason why I would want a binding listed that is unset. 2)If I wanted to reset the activation, I could do that directly through activation type.
So honestly, I think that the delete option should just fully remove the sub command/extra command.
