ScrollingBackground改名SpriteBackground

增加了一些功能，然后写了一个Demo,应该是蛮细致的...

+/* For demonstrating using one design resolution to match different resources,
+   or one resource to match different design resolutions.
+
+   [Situation 1] Using one design resolution to match different resources.
+     Please look into Appdelegate::applicationDidFinishLaunching.
+     We check current device frame size to decide which resource need to be selected.
+     So if you want to test this situation which said in title '[Situation 1]',
+     you should change ios simulator to different device(e.g. iphone, iphone-retina3.5, iphone-retina4.0, ipad, ipad-retina),
+     or change the window size in "proj.XXX/main.cpp" by "CCEGLView::setFrameSize" if you are using win32 or linux plaform
+     and modify "proj.mac/AppController.mm" by changing the window rectangle.
+
+   [Situation 2] Using one resource to match different design resolutions.
+     The coordinates in your codes is based on your current design resolution rather than resource size.
+     Therefore, your design resolution could be very large and your resource size could be small.
+     To test this, just define the marco 'TARGET_DESIGN_RESOLUTION_SIZE' to 'DESIGN_RESOLUTION_2048X1536'
+     and open iphone simulator or create a window of 480x320 size.
+
+   [Note] Normally, developer just need to define one design resolution(e.g. 960x640) with one or more resources.
