fix(drill): place spots found up to 15 m from the navmesh; count only this run's Oxide errors (#22)

Run 49: place.set.each was refused "4.4 m from the navmesh", because
OnMesh searched 3 m and returned the unsnapped point; Place now searches
15 m. The drill reported run 48's four error lines again: oxideErrors
read the whole day's Oxide log, and now reads only what was added after
the drill started the rig.
