Twisting vines use same sounds as weeping vines

The bug

Along with WEEPING_VINES, there exists a sound type called TWISTING_VINES, that has its pitches halved. Twisting vines do not use this, instead using weeping vines' sounds.
 

Solution

In Blocks.java, for TWISTING_VINES and TWISTING_VINES_PLANT, change the sounds to TWISTING_VINES.
