* ManualTests/forms/calendar-picker.html: Added stepBase parameters.

Source/WebCore:

Calendar picker should be using zero as default step base for input type=date.
The spec says to use zero unless specified otherwise.
Since input type=week has another default step base, I am adding step base
to DateTimeChooserParameters.

Test: fast/forms/date/calendar-picker-with-step.html

* Resources/pagepopups/calendarPicker.js:
(handleArgumentsTimeout):
(CalendarPicker):
(CalendarPicker.prototype.stepMismatch): Use the new this.stepBase.
* html/shadow/PickerIndicatorElement.cpp:
(WebCore::PickerIndicatorElement::openPopup): Gets step base from step range.
* platform/DateTimeChooser.h:
(DateTimeChooserParameters): Added stepBase.

Source/WebKit/chromium:

* src/DateTimeChooserImpl.cpp:
(WebKit::DateTimeChooserImpl::writeDocument): stepBase needs 11 digits of precision when setting maximum possible date.

LayoutTests:

* fast/forms/date/calendar-picker-with-step-expected.txt: Renamed from LayoutTests/fast/forms/date/calendar-picker-appearance-with-step-expected.txt.
* fast/forms/date/calendar-picker-with-step.html: Renamed from LayoutTests/fast/forms/date/calendar-picker-appearance-with-step.html. Renamed because this does not test apeparance.
