Android datepicker mode configurations added

Summary:
Currently, The **DatePickerAndroid** component opens the native date picker with default mode. We can't able to change the mode via configurations. To support android **[date-picker mode](https://developer.android.com/reference/android/widget/DatePicker.html)**, existing component needs to be changed.

**For Android >= 5.0**, The DatePickerDialog doesn't provide the default method to change the mode of a date picker.  So I have added custom theme which will support two kinds of **mode('spinner','calendar')** ref:https://developer.android.com/reference/android/R.attr.html#datePickerStyle.

**For Android < 5.0,** The DatePickerDialog provides the default method to change the mode of a date picker. ref:https://developer.android.com/reference/android/widget/DatePicker.html#setCalendarViewShown(boolean).

With the help of **Build.VERSION.SDK_INT** I have done the above functionality with limited lines of code changes and also I have added the example to UIExplorer.
