v1.0.8

Fixes:

• Fix some sight bugs when blinded:
  • Normally all 4 squares around you are unfogged. Then if any of those squares is not "opaque" then it unfogs any walls nearby.
    the code unfog the wrong neighbors.
  • Check whether surrounding squares are in bounds (otherwise will wrap to other side)
  • Monster's vision was accidentally seeing through walls when you're blind
