Update yellow arrow placement graphics on inserters

[bfayer]

It's not clear based on the current graphics where inserters pick and place to. For example, a normal inserter places on the further side of a belt but picks from both sides of a belt. The yellow line and arrow graphic during placement could be modified to represent this by shifting the line after the arrow over and by having a double yellow line on the picking side. The same for all other inserters

Well, I know what you mean (btw. they prefer to take from the inner lane), this is also useful for miners.

Good to know. The only reason I even figured out that they placed on the opposite side of a belt was from the tips at the beginning of a new game. I probably played 20 hours without realizing it on my own.
