v0.4.0

Added

• A new command prototool create to auto-generate Protobuf files from a
  template. The generated files have the Protobuf package, go_package,
  java_multiple_files, java_outer_classname, and java_package values set
  depending on the location of your file and config settings. Make sure to
  update your Vim plugin setup as well if using the Vim integration. See the
  documentation for prototool create in the README.md for more details.

Changed

• The values for java_multiple_files, java_outer_classname, and
  java_package that pass lint by default now reflect what is expected
  by the Google Cloud APIs file structure. See
  https://cloud.google.com/apis/design/file_structure for more details.
• protobuf format will now automatically update the value of go_package,
  java_multiple_files, java_outer_classname, and java_package to match
  what is expected in the default Style Guide. This functionality can be
  suppressed with the flag --no-rewrite. See the documentation for
  prototool format in the README.md for more details.
• Formatting configuration options are removed. We think there should be
  only one way to format, so we went with defaults of two spaces for indents,
  semicolons at the end of RPCs if there are no RPC options, and always
  having a newline at the end of a file.
