Ver. 1.0.1: Fix for Submerged Events

This is a generally recommended bugfix update.

Fixes:

• Submerged Events are now clickable.
  (enumerateEventsVisibleAt now tests also upper and lower body sprites, if present and visible.)

This is also relevant for the opaque part of Events that are only in part submerged, as that still uses a different sprite for display compared to when the Character is shown normally.
