Update time zone abbreviation lists for changes missed since 2006.
Most (all?) of Russia has moved to what's effectively year-round daylight savings time, so that the "standard" zone names now mean an hour later than they used to. Update that, notably changing MSK as per recent complaint from Sergey Konoplev, but also CHOT, GET, IRKT, KGT, KRAT, MAGT, NOVT, OMST, VLAT, YAKT, YEKT. The corresponding DST abbreviations are presumably now obsolete, but I left them in place with their old definitions, just to reduce any possible breakage from this change. Also add VOLT (Europe/Volgograd), which for some reason we never had before, as well as MIST (Antarctica/Macquarie), and fix obsolete definitions of MAWT, TKT, and WST.
