fix the logic: stop cycle when SliderLayout has only one SliderView

[yinyinnie]

当组件遇到一张图片的情况下，我个人觉得不需要自动轮播，并且也不需要手动滑动

Prevent conflicts with other components's "shape" attr, so modify attr "shape" to "daimajia_slider_shape"

I tried this fix, but when I have more than 1 slide, the autocycle doesn't start automatically anymore.

@Mauker1 I just intercept the touch event when layout have only one slide. I has tested the code, it's ok
