[1.4][SSP] When refueling with Sugar Cane, turtle.refuel() returns "true" but FuelLevel remains at 0

ComputerCraft Version Information: 1.4 Client in technic-v7.2.6 (also tested with 1.41)

Description of Bug:
When placing Sugar Cane in slot 1 and using either the Refuel program or turtle.refuel() function:
- the item is consumed but the fuel level does not change.
- the turtle.refuel() function returns "true"

The Wiki claims that the turtle will gain 3 movement per Sugar Cane.

On a sidenote the Wiki also claims that Mushrooms are a viable fuel source, but both kinds of Mushroom are rejected by the Turtle.
I did not test all Fuel sources, however Coal, Wood Blocks and Sticks worked as expected.

Im sorry for being unclear in my wiki edit, i was meaning mushroom blocks. However that sugar cane bug could be that its furnace value is so low that it gets into 0 movement(this would return true, because it is indeed a fuel) due to math.floors()

I think a work around would be to refuel with 8 suger cane at a time.

Fixed in next version due to diligent poking by Cruor.
