- rolled in a change from the KJS folks

	Fixes a bug where the date functions would not accept non-strings.
	And provides a bit of a speedup.

        * kjs/date_object.h: Change parameter type for parseDate.
        * kjs/date_object.cpp:
        (DateObjectFuncImp::call): Always call toString, don't check the type.
        (KJS::parseDate): Take a UString parameter, not a String parameter.
