Mollusk, Shadowbeast, Kriipa, Statue treasure profiles; new treasure items

Added treasure profiles for monsters that just had generic settings, and
added four new colors of mushroom intended to be used as treasure.

* Living statues now drop BDS at 6%, similar to Skeletons that spawn in
the same area. In addition, they drop scale, short swords, hammers,
axes, and knight's shields at low rates. They drop no money; instead
they drop large amounts of diamonds, rubies, and purple mushrooms. They
also drop edibles for convenience of building.

* Dragonflies are very similar to their former drops, but with their 15%
rainbow fern drop changed to money (now 42%).

* Kriipas drop a large amount of kriipa claws, and yrxl sap at the best
amounts in the game (10%). The rest is all money (60%).

* Mollusks had their crap cleaned up and converted to Money (61%). Their
drop rates for BDS (6%), Rubies (4%), and Inkies (4%) remain the same,
however they now have a 25% chance to drop a new Green Mushroom treasure.

* Shadowbeasts now drop less crap, more keys (5% up from 1%), and
large amounts of highly valuable Gray Mushrooms. BDS, DAFs, plate,
and mystic chances remain the same.

In general, all BDS, DAFs, and Inkies chances remained the same.
In addition to the treasure profiles, I added four new types of mushroom
intended to be valuable treasure past Rubies. The aim is to diversify
loot rather than just have mass money dropping, and these items can also
be used in the future for quests or other content.

* Green Mushrooms sell to Frisconar for 200.

* Yellow Mushrooms sell for 288. Not yet available normally.

* Gray Mushrooms sell for 360.

* Cyan mushrooms sell for 432. Not yet available normally.
