A dialog should appear if peforming an attack would turn an ally into an enemy

[DavidFidge]

Enhancement request - certain attacks such as lighting, poison, fire staves and offensive wands such as polymorphism cause your ally to turn into your enemy. The vast majority of these are simple user interface accidents like slips of the mouse. I propose that a warning prompt should appear, similar to the warning prompts that appear in other dangerous situations such as diving into depths.
