Rod of Recall and Transmogrification Chest can not be dropped

Overhauled transmogrification chest:<ul>
<li>A new inventory tabs appears for the chest</li>
<li>All items are automatically pickedup and put in the chest</li>
<li>Items in the chest are weightless</li>
<li>You can still transmogrify from the inventory menu</li>
<li>When you leave the current level all items in the chest are transmogrified automatically</li>
<li>In the inventory chest tab you can move an item out of the chest, it will then act as any other item, with an encumberance and be useable (and will not be transmogrified)</li>
</ul>
