[ANN] TimeZoneDatabase V1.2.4 on SqueakMap

TimeZoneDatabase is an Olson time zone database for Smalltalk, integrated
with Squeak Chronology.

  <http://en.wikipedia.org/wiki/Zoneinfo>

Changes since V1.2.3:

- Automatically load database from /usr/share/zoneinfo if available.

- Provide #buildDefaultUTCDatabase as a minimal database without requirement
  for external tzfile files if /usr/share/zoneinfo is not present.

- Fix TimeStamp class>>now to answer a TimeStamp (fixes bug reported
  by Lex Spoon for Universes distribution).

- Replace all '_' with ':=' for assignment characters. Method time
  stamps are preserved.

- Remove TimePlugin from the package to eliminate an unnecessary
  dependency on the plugin and VMMaker. TimePlugin is now in package
  VMConstruction-Plugins-TimePlugin.

- Update initialization to support loading from MCZ.

Development source is maintained on SqueakSource.
