[1.52][Bug?] Vanilla Hopper does not suck from Turtle slot 4

ComputerCraft version: 1.52
Minecraft Forge version: 7.7.1.652

Description of Bug:
Vanilla Hopper does not suck an item stack from slot 4 of a turtle inventory.

Steps to Reproduce Bug:

1. Place a Hopper
2. Place a Turtle on the hopper
3. Put an item stack into the slot 4 (upper right) of the turtle inventory

There is a private field in dan200.turtle.shared.TileEntityTurtle:

private static final int[] INVENTORY_SLOTS_MAIN = { 0, 1, 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };

I guess it should be fixed as follows:

private static final int[] INVENTORY_SLOTS_MAIN = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 };

Moved to Bugs section.

Approved this, not sure why was unapproved! Fixed for next ver.

Oh, I think I neglected to approve the topic after I moved it. :P/>
