Update zone.tab for Russia, and remove Asia/Tiksi comment.

Browse Source 
My best guess is that the Asia/Tiksi entry is a false alarm,
and that the area hasn't diverged from Yakutsk since 1970.
* europe: Move zone.tab comments to zone.tab.
(Asia/Yakutsk): Move comment for Bulunsky district here,
Remove a comment about a draft Asia/Tiksi zone, containing the
Bulunsky district.  We don't have sufficient evidence that it
ever diverged from Yakutsk after 1970.
* zone.tab (RU): Reorder entries to make more geographical sense.
Add comments for draft zones Asia/Chita, Asia/Srednekolymsk.
(Europe/Samara, Asia/Novokuznetsk, Asia/Magadan, Asia/Kamchatka)
(Asia/Anadyr): Mention that the Moscow offset changes 2014-10-26.
* NEWS: Document the above.

Changes affecting future time stamps
Russia most likely will subtract an hour from many of its time zones on
Russia most likely will subtract an hour from most of its time zones on
2014-10-26 at 02:00 local time. (Thanks to Alexander Krivenyshev.)
The affected zones are Europe/Kaliningrad, Europe/Moscow,
Europe/Simferopol, Europe/Volgograd, Asia/Yekaterinburg, Asia/Omsk,
Asia/Novosibirsk, Asia/Krasnoyarsk, Asia/Irkutsk, Asia/Yakutsk,
Asia/Vladivostok, Asia/Khandyga, Asia/Sakhalin, and Asia/Ust-Nera.
Asia/Magadan will have two hours subtracted. Asia/Novokuznetsk's time
zone abbreviation is affected, but not its UTC offset. It appears that
two new zones will be needed soon: Asia/Chita (split from Asia/Yakutsk,
and also with two hours subtracted) and Asia/Srednekolymsk (split from
Asia/Magadan, but with only one hour subtracted). (Thanks to Tim Parenti
for pointing out the need for the latter zone.) Additionally, a new zone
Asia/Tiksi (split from Asia/Vladivostok) will be needed to fix some history
before 2011. (Thanks to Tim Parenti.) All three of these new zones will
be deferred until the change is official; for now they are commented out.
There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky
Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug
(Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast
(Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic
(Europe/Samara) are not changing their clocks. The changed zones are
Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd,
Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk,
Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga,
Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours
subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected,
but not its UTC offset. Two new zones will be needed: Asia/Chita (split
from Asia/Yakutsk, and also with two hours subtracted) and
Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour
subtracted). (Thanks to Tim Parenti for much of the above.) New zones
will be deferred until the change is official, and are commented out for now.
