Additional folder created on saving file.

[JaguariBrawijaya]

Upon saving a recorded file in the HMM_VQ class, an additional folder is made inside of the Word folder, with the same name as the world folder. Attached is a picture when the said scenario occurs.

The issue occurs every time a file is saved, to reproduce the bug, this is the following action taken.

1. Record a new .wav file using the Record button in the JSoundCapture Panel
2. Proceed to change into Add Sample tab on the JTabbedPane
3. Changing the ComboBox into the word to save the sample.
4. A folder with the same name as the Word folder is made inside of the Word folder.

This is an issue cause the empty folder created at the word folder causes an error when generating codebook or training the HMM.
