Artifact effects: check for worn status before using effects_worn.

game::process_artifact is called when processing items in the characters inventory, it will be called for items in either the main inventory, worn items or the wielded item,
one has to check whether the item is actually worn or just wielded / carried before applying the effects.

Only print the message when item is not worn.
Remove the wielded parameter from game::process_artifact

As the worn status is calculated inside the function, why not also calculate the wielded status there?
The code is equivalent.
Remove game::fire

It has become nothing more than a wrapper.
Implement generalized "attitude towards creature" function.

While npc and monster have their own check of attitude towards the player, there is no such function for the Creature class.

This is just a placeholder until proper faction support gets implemented. Creatures should refer to their faction than.

However this allows for easy sorting of creatures based on their attitude for example when targeting with a gun.
Sort by creatures attitude when targeting with a gun.

List hostile creatures before neutral before friendly creatures.
With same attitude, sort by distance as before.

Make the code in game::target a bit simpler, the check for u.sees is already done in game::pl_target_ui, so just target the first creature of the list.
