[Fixed in 1.6] Cloned Repeaters do not hold their delay values

What's happening:
Cloned repeaters (2, 3 or 4 ticks) will show the good texture, but will act as 1 tick ones.

What's expected:
Cloned repeater should respect their values, even if cloned.

Step to reproduce:
Place a repeater, set it to 4 ticks clone it using /clone command and compare the speed of them.
