v1.2
General code clean-up:
- Refactored static methods in SecretDoor.java to SecretDoorHelper.java.
- Re-wrote the Block click EventHandler - much cleaner now.
- The previous fixed double doors.
- Fixed a bug where you could create a SecretDoor with another wooden door (woops!)
- Doors and attached items can now be clicked from any side and it opens the door properly
