Issue TIMOB-20008: iOS: Rename AlertDialog placeholder properties to hintText
The new {{*placeholder}} properties for the [AlertDialog|https://appcelerator.github.io/appc-docs/latest/#!/api/Titanium.UI.AlertDialog-property-placeholder] should be renamed to {{*HintText}} as that is the name we use on all other API's like [TextArea|https://appcelerator.github.io/appc-docs/latest/#!/api/Titanium.UI.TextArea-property-hintText].
