• Fix Grakn Core distribution for Windows
  Make Grakn Core distributions for Windows operational by adding previously lacking grakn.bat (a Windows-specific script to interact with Server and Console).

• Fix a concurrency bug in async producer which may result in illegal state exception
  Fix a concurrency bug in async producer which may result in illegal state exception.

• Improved the performance of data transactions
  We improved two aspects of data transaction behaviour. First, we removed unnecessary locking when the schema graph is in "read-only" mode. Second, we improved the performance of commit validation by reducing unnecessary stream parallelisation.

• Fixes to insert behaviour
  In upgrading BDD tests to cover insert behaviour as it should appear in grakn 2.0, a number of inconsistencies were revealed. We resolved these inconsistencies.

• Encoding enums allocate byte arrays once
  To prevent allocating too many byte array unnecessarily, we create Encoding byte arrays in each Enum's constructor, and always return the same instance. This means the GC and memory allocations don't have to kick as often.
