Remove references to AR::Observer from docs

ActiveRecord::Observer was extracted into a separate gem so it
should not be referenced anymore (see https://github.com/rails/rails/commit/ccecab3)

Remove references to AR::Observer from docs
Make `Time.zone.parse` to work with JavaScript date strings

Chrome, Safari and Firefox serialize Date objects to strings such
as 'Mon May 28 2012 00:00:00 GMT-0700 (PDT)'. When these strings
are parsed the zone is interpreted as 'GMT-0700' which doesn't
exist in the TzInfo list of timezones.

By taking advantage of the improved date/time handling in 1.9.3
we can use `Date._parse` and the `:offset` value which is parsed
correctly.

Three tests were amended to make them pass:

1.  test_parse_with_old_date

    This needed changing to a different value because the original
    value was before EST was adopted so was being changed to a
    LMT (Local Mean Time) value after the change. It didn't before
    because `DateTime` just has offsets from UTC not timezones.

2.  test_parse_should_not_black_out_system_timezone_dst_jump

    Changed the implementation of this test as the stubs were
    dependent on internal implementation details of the test.
    Confirmed that the modified test still failed when the
    implementation of `parse` was restored to pre-#5571.

3.  test_parse_should_black_out_app_timezone_dst_jump

    Ditto.

Closes #5770.
