ClearScript 7.4: Generic script objects now implement IDictionary<string, object>; added JavaScriptExtensions.ToEnumerable and ToAsyncEnumerable (GitHub Issue #494); DocumentAccessFlags.AllowCategoryMismatch now applies to system documents; added DocumentSettings.AsyncLoadCallback and DocumentAccessFlags.UseAsyncLoadCallback; implemented smarter and safer HeapExpansionMultiplier handling; added ValueRef utility classes; updated API documentation. Tested with V8 11.1.277.14.
