New standardised periods for volatility in watchlist

The watchlist now features additional columns for volatility periods adding to the longer term.

Historic volatility for 6M, 1Y, 2Y and 5Y calculated on daily closing prices can now be viewed directly in the watchlist, further enabling for screening and sorting to discover and isolate extremes or rank candidates of your selection.

As always, these can be added directly in the list by using the "+" icon to the right or in the column configuration by searching for "Volatility".
