Akka.Streams.TestKit 1.4.13

Maintenance Release for Akka.NET 1.4** Akka.NET v1.4.13 includes a number of bug fixes and enhancements: `AppVersion` now uses Assembly Version by Default** The new `AppVersion` setting, which is used to communicate application version numbers throughout Akka.Cluster and is used in scenarios such as Akka.Cluster.Sharding to help determine which nodes receive new shard allocations and which ones do not, now uses the following default HOCON setting: ``` akka.cluster.app-version = assembly-version ``` By default now the `AppVersion` communicated inside Akka.Cluster `Member` events uses the `Major.Minor.BuildNumber` from the `Assembly.GetEntryssembly()` or `Assembly.GetExecutingAssembly()` (in case the `EntryAssembly` is `null`). That way any updates made to your executable's (i.e. the .dll that hosts `Program.cs`) version number will be automatically reflected in the cluster now without Akka.NET developers having to set an additional configuration value during deployments.
