Forex Session Breaks DST AWARE!

There seems to be no open source forex trading session DST (Daylight Savings Time) aware scripts which I think is absurd. This amazing community deserves better. So I adapted some code by icostan adding DST capabilities.

Original code by icostan here

I added DST code. Warning may not be perfect yet. Could be a bug or two. It only supports 3 major sessions right now but you can add your own rules for the other timezones by copying my logic.

It is open source so please add the other sessions and regions as needed and update me please.
