Charset Block Carry 0.5.4.6

Charset's Block Carrying lets you place chests in minecarts, which overlaps with Quark's "Right-click to place a chest in the cart." It's technically different (because you're carrying the chest block in the former and the chest item in the latter), but still overlapping functionality.
