---- No more first remove menu and then build, but "refresh"...
Fixed boarding process when a carrier would ascend while boarding, the
boarding process would be cancelled by the cargo. the carrier is
notified of that event. When the carrier lands again, he can again board
the cargo using the cargo menu options.
When unboarding, the cargo would it the client helicopter on the path,
this is fixed by positioning the cargo at the direction of the target
unboarding point. No helicopter anymore in between.
