4.1.13:

Core:
* Fixed an issue with data values not ending up as 0 after setting block
locations to empty (causing infinite crop harvesting with the planter)
* Minor optimization for getting block drops
* All types of chests are now considered non-solid, meaning they can no
longer be used as building blocks in the builders. This prevents a
builder from building a long line of connected (and bugged) chests.

Planter:
* Reworked planter internals to be more readable and maintainable
* Following Minecraft's nerf of bonemeal, using it in the planter no
longer instantly grows a crop to full. It now advances most crops
randomly by 2-5 growth stages.
* Cocoa bean farming! (place logs to the sides)

RedstoneBridge:
* Updated for 1.5.1
