Property: remove deprecation comment on value()

I don't think there is any plan to remove Property::value() as there is no reasonable alternative to it for non-POD properties (e.g. myMapProperty.value().at()).

This comment recently caused some confusion amongst ATLAS developers what the appropriate way to get access to the value should be.

I agree with you... and it's not just about non-POD type as demonstrated by !1413 (merged)
