Allow reading fun books even when morale is low
Initial changes made to allow resizing the ingame viewport.
Removed some overzealous corrections made last commit, and fixed NPC/mob position scaling on the UI.\nAdded a couple lines to the Makefile where the desired viewport size can be set.
Tweaked the Makefile again, fixed footsteps, a few other effects, and attempted to fix targeting.\nAlso made an adjustment to the "list items" search radius.
