Silk Suspicious Sand

This mod adds some features to enhance the Archeology update of Minecraft

* Suspicious blocks can now be picked up with silk touch when before they would drop nothing.

* The brush can now be enchanted with efficiency which adds +1 stroke per level making brushing faster.

* Adding fortune to the brush decreases the chance that the brushed block reverts to it's original form after each artifact leading to more average artifacts per block.
