Improvements for Slime Processor and Monkey Recycler. (Xenobiology)

* Dead monkeys can now be directly drag'n'dropped into Xenobiology's Monkey Recycler.
* Dead slimes and monkeys can now be directly drag'n'dropped into Xenobiology's Slime Processor.

Regular food can also be processed by drag'n'drop into kitchen's processor now.
But this should make Xenobiology a thousand times more agreeable.
Can't qdel mobs very well.
