Change player draw state when quick-selecting weapon or spell.

Behavior is mostly similar to vanilla Morrowind - the only difference is that in vanilla Morrowind, quick selecting between weapons while one is already out would not play an animation, but would just instantly change the weapon model in the player's hand. Here, the weapon draw animation is played if a quick-selected weapon is different from the one in the player's hand.
 * Drawing is not exclusive to Weapons. You can also draw Lockpicks and Probes, for example.
 * If the use action failed (e.g. a broken weapon), then we should not try to draw it.

Both cases should be fixed by replacing the check with a "does the player now have the item equipped on the right hand"?
