Slow and fast motion in physic

Hi, I never test this in simulator, but it works fine in browser.

I’m still stuck with this - can not get slow motion running on devices.
@slackmoehrle, @zhangbin: could you get a look at this, please!

to slow down I found a 1 line solution

cc.game.config[‘frameRate’] = 60; //default is 60, doing 120 will slow down physics to half

it works for me
