Added message handling code for cruor drops in abyssea.

This won't make cruor drop till someone creates code to handle cruor chaining or edits their copy for non retail amounts however. As long as the text IDs I added in ea9724b07cf310476d1ba1a838f386c6ea42d734 a few days ago stay updated, this will work properly.
I put it to see Pzone == 182 (Walk of echoes)
