Creating a global level helper function (Alpaca.handleFieldInitialState) to wrap the functionality governing the initial validation refresh and deactivation of the hideInitValidationError flag.  This extracts out the functionality from the Alpaca._init function so that it can be used elsewhere (leaving the original code commented out in that location for the time being, just in case a revert or revisions are necessary).  The reason for doing this is to expose the same functionality to the ArrayField class to be run on creation of a new element using the Add button (both on the toolbar and the initial Add Item).  Previously, any array children with this flag would never have it deactivated, which caused a bit of confusion around array element validation states.
