0.5

v0.5: A major release, that makes backwards incompatible changes to
the generated code for the C backend.

  The intent is for this release to be the last API-breaking one
  before 2.0.

  IMPORTANT: This release includes backwards incompatibilities. In
  order to use it, you will need to add hooks for message
  passing. See the parts of the tutorial that deal with
  Handle_Message and Send_Message for details. In addition, some
  names generated by Smudge may have been changed. If you use
  anything other than alphanumeric characters for the names of
  your state machines and events, you will have to update your
  C code.

  Features: Adds message passing hooks for user code to queue
  events. Most names are now prettier. Added memory management
  hooks for freeing events.

  Documentation: Updated the tutorial to include the new and
  exciting features.

  Architecture: Replaced monolithic C backend with SmudgeIR
  intermediate representation.
