Handle division by zero in Bollinger Band pband
 
There are times when for the whole period of Bollinger Band no price changes happen. Thus, top/bottom/mid and close are all the same. In this case pband calculation cause div by zero. This change would set it to NaN in these cases. Indeed, there is no good default - the price "touches" all three lines at the same time.
