Request: allow to use the new androidExtensions way

[AndroidDeveloperLB]

It's much shorter code:

gradle file:

apply plugin: 'org.jetbrains.kotlin.android.extensions'
androidExtensions {
experimental = true
}

sample code of a class with 3 Dates in it:

@SuppressLint("ParcelCreator")
@Parcelize
class MonthItem(val today: Date, val startDate: Date, val endDate: Date) : Parcelable {
}

The plugin here will only ask us which fields to add there, and which to ignore. Maybe also the order.
