Further changes to fix issue 574\685.
There appear to be some additional problems with the impact of daylight
savings time kicking in. Calculations of BIAS, Standard BIAS &
Daylight BIAS are wrong.
This is showing up with Outlook 2010 meeting appointments, for example
select America\Vancouver, appointments, once accepted get assigned an hour
early.
I have also applied a fix to correctly send the Timezone information
currently commented out of code referencing this issue number in
libfreerdp_locale/timezone.c function freerdp_time_zone_detect()
