Hero always centered in camera in new hero levels when playing and not panning to drag.
No more ThangListView for hero levels. Fixed pluralization of level loading goals when there's only one goal. Fixed default playback state to paused. Started playing ambient dungeon/grass sounds. Fixed bug with goals not showing up at first. Refactored how goals, gold, and flags hide themselves initially. Ignored InventoryView ThangTypes when sorting Components during level serialization.
Merge branch 'master' into production
