Improved spelunking — Heroes of a Broken Land 2 Steam update #756607

This update fixes the lack of decorations in caves, you should now find them filled with the usual objects and decorations as other dungeons. Most of the other work in this version is internal - multi-party support is approaching completion, but one large task remains before it's ready for release. It's taken longer than anticipated, which means it's been a while since players have seen much visible updates. So in the meantime I'll be spending some time on more player facing updates over the next few weeks, nothing too major, but likely some balance tweaks and starting the finish off the UI (mostly missing icons to start). Changes: Fix caves not having enough decoration Fix mini map switches on multi floor dungeons
