Tomb Many Graves

NOTE: This update changed the way rendering works; all current, in-world graves will be replaced with the "floating head" variety upon update. The contents of the graves will not change (or, at least, they shouldn't...)

Changed:

• Grave rendering
  • Textures are no longer "squished" as before
  • More types of blocks are able to be used as a grave texture

Added:

• A config to allow graves to replace crops (anything that implements IPlantable - saplings/flowers/crops/etc)
