add tests-boot-js-for-obfuscation.js as an entry

1. Add tests-boot-js-for-obfuscation.js, 
After obfuscation, all js files will be combined to one "game.js". So all "require" keywords should be removed, otherwise "can not find xxx.js" errors will raise.

2. Fixes  js grammars in PerformanceAnimationTest.js, which would lead google closure compiler to compilation failure.
