TimeZone: fix base offset for Sri Jayawardenepura. Anchor tests for zone offsets to more current date

Namespace Inflector, Dependencies, OrderedOptions, and TimeZone under ActiveSupport [#238 state:resolved]

TimeZone#to_s shows offset as GMT instead of UTC, because GMT will be more familiar to end users (see time zone selects used by Windows OS, google.com and yahoo.com.) Reverts [8370]

Time.zone.parse: compatibility with far future date with time zone offset in string. Eliminate creation of additional TimeWithZone instance to determine utc offset.

Fix Time.zone.parse from stripping time zone information and make Time aware attribute methods use Time.zone.parse instead of to_time

Bundling abbreviated version of TZInfo gem 0.3.8: only the classes and zone definitions required to support Rails time zone features are included. If a recent version of the full TZInfo gem is installed, this will take precedence over the bundled version

Time.zone= accepts TZInfo::Timezone instances and Olson identifiers; wraps result in TimeZone instance

Make TimeWithZone work with tzinfo 0.2.x: use TZInfo::Timezone#zone_identifier alias for #abbreviation, silence warnings on tests. Raise LoadError when TZInfo version is < 0.2 by sniffing for TZInfo::TimeOrDateTime constant. Move all tzinfo-dependent TimeZone tests into uses_tzinfo block

TZInfo caches Timezone instances in its own internal hash cache, so TimeZone::MAPPING doesn't need to cache them as well

TimeWithZone caches TZInfo::TimezonePeriod used for time conversion so that it can be reused, and enforces DST rules correctly when instance is created from a local time

Replace non-dst-aware TimeZone class with dst-aware class from tzinfo_timezone plugin. TimeZone#adjust and #unadjust are no longer available; tzinfo gem must now be present in order to perform time zone calculations, via #local_to_utc and #utc_to_local methods.
