Title: bring Spritebuilder+SK submodule up to date, fix crash with cocos2d version upgrade

Version upgrade crash: at least when running a debug build and the message pops up, and you click "Ignore this version" the app crashes due to _spritebuildersCocos2dVersion being nil and being added to an array. Happened multiple times reproducible so I added a not-nil check there.
