bug: TreasureCount can be over the limit

[OneCricketeer]

Observed: Going over the treasure limit is possible (can collect more treasure after ladder is extended)

Since the ladder still works as expected, this is minor issue...

Questions:

• Can guards pickup more than one treasure?
  • The hasTreasure is a boolean, so "no", but is this checked when they collide with another treasure?
• When they die (brick or armor), do they properly release their treasure(s)?
  • The treasure block appears where they die, but when they respawn, do they still have a treasure?
• During collision detection, when looping over treasure blocks, are we not breaking the loop? I.e if there are multiple treasures on the same coordinate, all should be collected, and not over-counted.
