Warning on on-ramps

Many mappers that hadn't followed the discussion, thought the on-ramps were forgotten when the reduced speed limit was mapped in Openstreetmap. So they changed the correct speed limit of 130 km/h to 100 km/h. To prevent this a warning is added to the on-ramps in the tag note:maxspeed=* with the text "Counterintuitively, the maxspeed on this on-ramp is 130 km/h instead of the lower speed posted on the main road due to it having only a G1 (start motorway) sign at the start".
