Summary:
I have an issue when combining `PullToRefreshViewAndroid` and `ViewPagerAndroid`.
`ViewPagerAndroid` will not able to scroll that gesture handler is being taken by `PullToRefreshViewAndroid`
One solution is to disable `PullToRefreshViewAndroid` if `ViewPagerAndroid` is scrolling (i.e. not idle).
[Reference solution here](http://stackoverflow.com/a/29946734/2590265)
So here need to expose the `onPageScrollStateChanged` event.
Some code referenced from DrawerLayoutAndroid, especially the `VIEWPAGER_PAGE_SCROLL_STATES` array.
Please feel free give me comments.
Thanks.

Summary: public
RCTUIManager is a public module with several useful methods, however, unlike most such modules, it does not have a JS wrapper that would allow it to be required directly.
Besides making it more cumbersome to use, this also makes it impossible to modify the UIManager API, or smooth over differences between platforms in the JS layer without breaking all of the call sites.
This diff adds a simple JS wrapper file for the UIManager module to make it easier to work with.

Summary: In some cases it's desirable to set the page in the ViewPager without animating it -- we have this in ScrollView with `scrollWithoutAnimationTo`. This PR adds `setPageWithoutAnimation` on ViewPager.
