first pass at Uyghur time

[Arthur David Olson]

Below find a first pass at changes to "zone.tabb" and "asia" to handle Uyghur variants of time in China.
The basic approach is to have zones with Han-based names for the rules used by Han,
and zones with Uyghur-based names for the rules used by Uyghur.

! # From Luther Ma (2009-10-17):
! # Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
! # Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
! # but have no need of it. All planes, trains, and schools function on
! # what is called "Beijing time." When Han make an appointment in Chinese
! # they implicitly use Beijing time.
! #
! # On the other hand, ethnic Uyghurs, who make up about half the
! # population of Xinjiang, typically use "Xinjiang time" which is two
! # hours behind Beijing time, or UTC +0600. The government of the Xinjiang
! # Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
! # local governments such as the Urumqi city government use both times in
! # publications, referring to what is popularly called Xinjiang time as
! # "Urumqi time." When Uyghurs make an appointment in the Uyghur language
! # they almost invariably use Xinjiang time.
! #
! # (Their ethnic Han compatriots would typically have no clue of its
! # widespread use, however, because so extremely few of them are fluent in
! # Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
! #
! # (...As with the rest of China there was a brief interval ending in 1990
! # or 1991 when summer time was in use.  The confusion was severe, with
! # the province not having dual times but four times in use at the same
! # time. Some areas remained on standard Xinjiang time or Beijing time and
! # others moving their clocks ahead.)
! #
! # ...an example of an official website using of Urumqi time.

! # From Luther Ma (2009-11-19):
! # With the risk of being redundant to previous answers these are the most common
! # English "transliterations" (w/o using non-English symbols):
! #
! # 1. Wulumuqi...
! # 2. Kashi...
! # 3. Urumqi...
! # 4. Kashgar...
! # ...
! # 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the
! # 1960's. I know of one Han, now over 50, who grew up in the surrounding
! # countryside and used Xinjiang time as a child.
! #
! # 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
! # start date for Xinjiang time.
! #
! # Without having access to local historical records, nor the ability to legally
! # publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
! # Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
! # not be using Beijing time, but some local time.)
! 
! # From Arthur David Olson (2009-11-21)
! # Use English transliterations of Han names of cities for names of zones using Han approaches;
! # use English transliterations of Uyghur names of cities for names of zones using Uyghur approaches.
! # Since (reportedly) at least some Uyghur have observed Beijing DST rules,
! # use PRC rules for Uyghur zones.
