Added gpnf_submitted_nested_entries hook. (#20)

Fixed issue where child entries would not be attached to the proper entry when used in conjunction with the WooCommerce Gravity Forms Product Add-ons plugin.

Fixed issue where GP Nested Forms would cause the form buttons to change when using multiple forms on a given page in conjunction with GravityView.
Fixed issue where scrollbar did not work correctly when the modal was open by updating Tingle to v0.15.3.
Reverted stop-gap fix for {Parent} merge tag compatibility with Populate Anything. Fixed in Populate Anything 1.0-beta-4.54.
