Tekkit Classic Rubber Farming

Makes the IC2 rubber log look like this when it's ready to harvest. Makes it a lot easier to spot them when they're hidden among hundreds of others.

!Two rubber logs floating in the air with a red arrow pointing from the left one to the right one. The left log is a normal IC2 rubber log with a spot of harvestable rubber on its left face. The right log looks exactly the same, except for its left face, which is completely orange rather than having just a small spot of orange like the left log.
