1.1.0-beta1

• A IOException: Not enough storage is available to process this command
  when using the memory-mapped mode with 32-bit builds or many threads was
  fixed. Closes GH #5.
• Use of streams was replaced with direct access for both the memory-mapped
  file mode and the memory mode. This should increase performance in most
  cases.
• When using memory-mapped mode, the file is now opened with
  FileShare.Delete, allowing other processes to delete or replace the
  database when it is in use. The reader object will continue using the old
  database.
• The Json.NET dependency was updated to 7.0.1.
