KBI Enriched Gravel

-Changed: Built around Forge 678 instead of 608; should still be compatible with older versions
-Added: support for ThaumCraft 3's Amber (as a direct drop); has same chance as obsidian chunks and chips of ruby, sapphire, and green sapphire
-Added: an amber gem item for when TC3 is not installed; can be crafted back and forth with TC3 amber to interchange, and both are registered as gemAmber in the Ore Dictionary
-Added: support for Thermal Expansion's sulfur to be crafted to and from piles of sulfur
-Added: Jade chips at same chance as gold and silver; I don't know of any other mod that uses Jade but it's got the usual gem OreDict registrations and I plan on using it myself
-Added: support for Karuberu's Mud Mod, in the same way with mud blobs as Amber, but mud is more common, of course
-Added: Karuberu's Peat Bricks to "brickPeat" in the OreDictionary, allowing peat chunks to be crafted into them
-Changed: If the Resources module is disabled, the Sturdy Sifter can be crafted with gold nuggets instead of iron nuggets, though if another mod like ThaumCraft or Thermal Expansion or GregTech adds iron nuggets, you can still use those. If you disable Resources and don't have a mod that adds alumin(i)um nuggets, turn "Enable aluminum nuggets in Sifter Block recipe" in Enriched Gravel.cfg to false to use the other two recipes.
-"Added": Red Rock chunks. I wanted to do this in the original release but there was no OreDictionary for it, and I didn't want to do reflection right away. But now I am doing reflection, so you have throwable red rock chunks that are compatible with both ExtraBiomes and Biomes O'Plenty.
-Added: At the suggestion of Karuberu, a new API file, CustomSifterDropAPI, which allows modders to add extra functionality to the Sifter Block. It's now used internally to make sand blocks sift into 4 sand piles 9/10 times, and 3 sand piles and a clay ball 1/10 times. It's metadata-sensitive, and supports constant drops, random drops, and null drops (set the itemstack parameter's itemID to 0, like, new ItemStack(0, 0, 0)). Blocks don't have to naturally be affected by gravity for this to work at the moment.
-Fixed: handheld sifters not causing a block update, meaning gravel above a sifted block would float in mid-air
-Fixed: using a water or lava bucket on gravel giving a gravel bucket (I seriously thought the event was only fired by empty buckets... my bad)
-Added: Cracked Sand piles, compatible with EBXL
-Added: Sound effect to the Sifter Block

Caveats

All types of enriched gravel appear as "Slightly enriched" with NEI's block identification thingy, and with the Pick Block feature. Consider this an exploit prevention.
