• Renamed 6 methods in the Java-native interface, to avoid underscores:

  • CollisionSpace.rayTest_native()
  • CollisionSpace.sweepTest_native()
  • PhysicsGhostObject.addOverlappingObject_native()
  • PhysicsSpace.postTick_native()

• Changed the Java API:
  • Added a static qualifier to the listPointIds() method in the PersistentManifolds class.
  • Privatized the getCollisionFlags() method in the PhysicsCollisionObject class.
• Bugfix: jmeCollisionSpace::m_pEnv gets modified during callbacks
• Publicized another constructor of the IndexedMesh class.
