Characters lines during unavailable operaions with their items

[DarkTl]

All cases when a character refuses to give away an item should lead to one set of lines. That includes attempts to discard items.
Although, since we have at least two different screens to transfer items, it might not be possible to make them use the same set.

All cases when a character refuses to equip an item should also lead to one set of lines. Different from the previous one.
