Auto fill in trigger -> auto delete triggers + delete patterns when playing

[XORadmin]

I think it makes sense when auto trigger insert is enabled then the trigger should also auto be deleted when deleting the note.
I will think about an extra option in the setup or automatically do it if auto trigger insertion enabled .

For the 2nd:
This is in design at the moment. Basically it is an issue i got to tackle at some point but don't give it a too high priority.
Basically i deny deleting (and mark/copy paste) so any playing pattern are not deleted or overwritten while playing and cause a general crash. Playing something that isn't there causes problems.
