TransitionSlideIn APIs seem to have bugs?

I just tested TransitionSlideInT api with cocos code IDE, it behaves differently in ios,mac simulator and browser…
the direction is opposite in browse than in mac and ios simulator…

test API: TransitionSlideInT
cocos2d-js version: 3.0RC1
IDE: cocos code IDE Mac OS X 1.0.0-RC0

I have fixed it in this PR:

It’s so easy to ignore this mistake, thanks for your feed back!
