Feature: new slot AMAZON.DATAPAST and AMAZON.TIMEPAST that only delivers dates and times in the past. If the user clearly asks for dates and times in the future ("next monday") the slot should deliver an error.

Reason: We have skills with slots AMAZON.DATE, which only refer to dates in the past. Currently AMAZON.DATE defaults to dates in the future and it is very hard to get dates in the past from that slot. We work around that in our code but that is error prone and annoying.

There are also many skills out there, where dates only refer to dates in the future. Therefor a slot AMAZON.DATEFUTURE and AMAZON.TIMEFUTURE would make sense.

I read many complains about the AMAZON.DATE slot and I'm convinced that if we had slots that distinguisch between past and future, many skills would work a lot better.
