BETA patch b.6

Fixed some silly nonsense with offstage spheres
Fixed some silly nonsense with the Wisdoms
You know if you clicked and dragged a wisdom node it appeared to do nothing but actually scrolled the hidden map? It doesn't now though.
Plaques less obtrusive (WIP tho)
Abandoned objects harder to lose
Fixed ridiculous bug where an object would sometimes slide mischievously behind a portage slot and become inaccessible
Lone autumnal tree in summer now retains summer colouring
Postmistress will now change a half crown",
