Fix Ruby's Time marshaling bug in pre-1.9 versions of Ruby: utc instances are now correctly unmarshaled with a utc zone instead of the system local zone [#900 state:resolved]

Fix TimeWithZone unmarshaling: coerce unmarshaled Time instances to utc, because Ruby's marshaling of Time instances doesn't respect the zone

Move test related core_ext stuff out of regular core ext to prevent nasty surprises when you require active_support then use Test::Unit directly.

TimeWithZone: when crossing DST boundary, treat Durations of days, months or years as variable-length, and all other values as absolute length. A time + 24.hours will advance exactly 24 hours, but a time + 1.day will advance 23-25 hours, depending on the day. Ensure consistent behavior across all advancing methods.

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]

Adding Date.current, which returns Time.zone.today if config.time_zone is set; otherwise returns Date.today. ActionView date_helper uses Date.current to determine locale-appropriate default

TimeWithZone: date part getter methods (#year #mon #day etc) are defined on class; no longer relying on method_missing

Duration #since and #ago with no argument (e.g., 5.days.ago) return TimeWithZone when config.time_zone is set. Introducing Time.current, which returns Time.zone.now if config.time_zone is set, otherwise just returns Time.now

Add config.active_support.escape_html_entities_in_json to allow disabling of html entity escaping.  [rick]
