Enhancements

• References librdkafka v1.2.0. Refer to the release notes for more information. Headline feature is consumer side support for transactions.
• Added IDictionary overload to Config constructors (contribution by @AndyPook).
• Confluent.Kafka, Confluent.SchemaRegistry and Confluent.SchemaRegistry.Serdes are now all signed, and Confluent.Kafka.StrongName depreciated.

Fixes

• Updated the librdkafka build load order so that the most featureful version is used on any given platform.
