FlowerPot canBlockPlaceAt()

I just recently started using github so I'm not sure how to make pull requests yet, that's why I'm posting here.

Basicly,

    public boolean canPlaceBlockAt(World worldIn, BlockPos pos)
    {
        return super.canPlaceBlockAt(worldIn, pos) && worldIn.getBlockState(pos.down()).isFullyOpaque();
    }

    /**
     * Called when a neighboring block was changed and marks that this state should perform any checks during a neighbor
     * change. Cases may include when redstone power is updated, cactus blocks popping off due to a neighboring solid
     * block, etc.
     */
    public void neighborChanged(IBlockState state, World worldIn, BlockPos pos, Block blockIn, BlockPos fromPos)
    {
        if (!worldIn.getBlockState(pos.down()).isFullyOpaque())
        {
            this.dropBlockAsItem(worldIn, pos, state, 0);
            worldIn.setBlockToAir(pos);
        }
    }

with the code above if you have any block that isn't a full cube but has a solid top, you can't place Flower Pots on top. I suggest changing it to work like torches, instead of checking if block below is a full cube, check if it has a solid top.

    public boolean canPlaceBlockAt(World worldIn, BlockPos pos)
    {
        return super.canPlaceBlockAt(worldIn, pos) && worldIn.getBlockState(pos.down()).isSideSolid(worldIn, pos, EnumFacing.UP);
    }

    /**
     * Called when a neighboring block was changed and marks that this state should perform any checks during a neighbor
     * change. Cases may include when redstone power is updated, cactus blocks popping off due to a neighboring solid
     * block, etc.
     */
    public void neighborChanged(IBlockState state, World worldIn, BlockPos pos, Block blockIn, BlockPos fromPos)
    {
        if (!worldIn.getBlockState(pos.down()).isSideSolid(worldIn, pos, EnumFacing.UP))
        {
            this.dropBlockAsItem(worldIn, pos, state, 0);
            worldIn.setBlockToAir(pos);
        }
    }
