Added ccFPSImages entity as linked resource

In eclipse, when HelloCpp or another project trying to compile you get:

../../../../../cocos2dx/proj.linux/Debug64/libcocos2d.so: undefined reference to `cc_fps_images_len'
../../../../../cocos2dx/proj.linux/Debug64/libcocos2d.so: undefined reference to `cc_fps_images_png'

I think that is the correct solution, because both files are added in the makefile and because of this compiling by console works perfectly.

Thanks and greetings!
