The Ti.UI.Picker view's datePickerStyle is currently iOS only. We should add support on Android. In particular, we should add the "compact" style which shows the picker as a read-only text field, and when tapped on, show a date/time selection dialog which matches Google's design guidelines.
The "datePickerStyle" property needs to be supported by the following types on Android:
Copy the following constants from Ti.UI.iOS to Ti.UI. Using the old constants should cause a deprecation warning on iOS.
If the Android only boolean properties useSpinner or nativeSpinner are defined, then they must take priority over the datePickerStyle property to maintain backward compatibility. When these boolean properties are set true, then they must do the equivalent of DATE_PICKER_STYLE_WHEELS.
