basic debug mode
Merge branch 'master' into peoplePlacement
lobby people done
hallway populated
fixed sorting in hall
moving start to lobby
added thought_group to Person
added currentAttachment to public variables
whitespace refactor
reorganized layers with proper sorting

background -> midground -> textground -> [foreground] -> overlay.
 background is for sprites
 midground is for characters and props (almost everything really)
 textground is for callouts
 overlay is for title screens.
foreground is not yet implemented, and I doubt we would need it.
top-level groups (layers) are sorted manually, while sub-groups are
y-axis sorted.

The current player's text callout will hop to the top of the
textground layer when they become active.
