BBF  and DST update

I have re-written the scripts on the server to access the data directly rather than relying on the system getting the DST times right for all time zones - When they are accessed the system is trying to be too clever and guessing the timezone from the point of access - which is incorrect for the Android application because all access is done via a secondary layer to ensure absolute security...

The access should be slightly quicker and the resultant data GMT based which suits the Android app better...

Hopefully no more having to press refresh every day - but I can only test it at midnight :-P
