Title: Change self.textView.backgroundColor to clearColor

I changed self.textView.backgroundColor to [UIColor clearColor].
And modified setBackgroundColor to change only self.backgroundColor.

I changed these because when the backgroundColor is set to a translucent
color, internal UITextView's backgroundColor and JTSTextView's
backgroundColor will be mixed and get darker than expected.
