Now change the Theme to Xianjian
Menu can work ugly, added menu.cpph menuManager.cpph
can change the background in the different scene
world2 and world3 are allocated dynamically now,
add the explodingPlayer and thePlayer

just like the explodingEnemy and theEnemy in manager.cpp,
this two pointers are used for exploding.

replaced all the player.xxxx to thePlayer->xxxxx , the code works
fine by present.
