Xamarin.Forms 1.4.3.6372

## Enhancements ## - Android ActivityIndicator Color property now works for Android 5.0+ - WinPhone 8.0 ActivityIndicator Color property now works - [WinRT] Now properly supports Color.Accent - [WinRT] Assorted performance and correctness fixes - [WinRT] PageRenderer.OnElementChanged is now virtual - [Android] Properly support `DatePicker.MinimumDate` and `DatePicker.MaximumDate` - [Xaml] Speed up parsing/understand of predefined colors by removing reflection - [Docs] Add documentation for missing summaries - [Core] Binding now supports binding to dynamic objects, such a json objects. ## API Changes ## `Xamarin.Forms.ItemsView` now contains a `protected virtual void UnhookContent (TVisual content)` method. This method is used for unhooking or otherwise cleaning content after usage. While the risk is low, this can be a breaking change for you app if you happen to have provided a method with the same name and the same parameters on a subclass of `ItemsView`, e.g. `ListView`. Please check your code if this is the case. ## Bug Fixes ## - [Bug 31029](https://bugzilla.xamarin.com/show_bug.cgi?id=31029) - [Windows Phone 8.1]Generating an Image via MemoryStream does not appear -
