Simple fix when extending BlockPane

In BlockPane, this:

    public final boolean canThisPaneConnectToThisBlockID(int par1)
    {
        return Block.opaqueCubeLookup[par1] || par1 == this.blockID || par1 == Block.glass.blockID;
    }

needs to be changed to this:

    public boolean canThisPaneConnectToThisBlockID(int par1)
    {
        return Block.opaqueCubeLookup[par1] || par1 == this.blockID || par1 == Block.glass.blockID;
    }

It feels sloppy being force to do this in the constructor to allow blocks extending blockpane to connect with thin glass or iron fences:

Block.opaqueCubeLookup[myblockid] = true;
Block.opaqueCubeLookup[block.fenceIron.blockID] = true;
Block.opaqueCubeLookup[block.thinGlass.blockID] = true;

btw, this setting is separate from  what returns from isOpaqueBlock or isNormalBlock, so changing it does not effect rendering from what I have seen, it seems opaqueCubeLookup is a behavioral mapping, so this work around doesn't cause too many issues, but obviously is could if something is truely expecting an opaque block by looking in there.
