This:
- Renames Entity.js-helper to PositionHelper.js for that name seems to fit better.
- Moves to that file:
- EntitiesNearPoint (from Attacking.js).
- InterpolatedLocation (from Attacking.js).
- TestCollision (from Attacking.js).
- PredictTimeToTarget (from Attack.js).
- Adds a test for the helper.
- Removes the svn:executable propset.
