Runes can be targeted by Ally units and destroyed.

This promotes (intentional or not) grief and mishaps when someone attacks an enemy who is standing on top of a rune.

Additionally, Ghastly Strike from Ghost can also target and be used on allies, even if the skill description says it's enemy-only.

Gravestones can also be destroyed by ally units. I believe destroyable objects in general can be destroyed by its ally units.

I've adjusted it to where you will only attack field objects that have an enemy placer or no placer.
