Training dummy reset

[Mhaeric]

I like the addition of being able to manually reset the enmity of a training dummy, but there's a few things that could improve it.

1. It completely replaced being able to reset it by running away. Please turn this back on as an additional way to reset the enmity. If I've run far enough away that I lose targeting on it, it should just automatically reset without needing to manually reset it.

2. It took me quite a while to figure out how to actually turn it off and I ended up resorting to asking how in novice network. I knew there was a context menu to bring up with the subcommand keybind, but I was trying to right-click on the dummy itself and on the dummy in my enemy list among other things instead of the GUI element for the active target. Adding a context menu to one or both of those would be very helpful.
