其实在实际项目中, 大多数 Pixi的用户 并不会使用 PIXI.ticker.shared , 而且 PIXI的ticker设计的并不好.

所以 这个PR 为DragonBonesJS pixi版本增加了 是否使用 PIXI.ticker.shared 的参数.

参数默认值 是 true, 所以这个改变并不会影响现有的项目.

用法:
```
    dragonBones.PixiFactory.useSharedTicker = false;
    var factory = dragonBones.PixiFactory.factory;

     // 此时 不会使用 PIXI.ticker.shared

    //   用户可以在 自己的 game loop 函数里使用 下面的方法来更新动画
    dragonBones.PixiFactory.advanceTime(passedTime);
```
