0.2.13

• New: Project instances can now have multiple repositories. Thus the
  repository attribute is renamed to repositories. And the order of the
  items in the repositories attribute is restored correctly.
• New: stalker.db.init() now automatically creates environment
  variables for each repository in the database.
• New: Added a new after_insert which listens Repository instance
  inserts to automatically add environment variables for the newly inserted
  repositories.
• Update: Repository.make_relative() now handles paths with environment
  variables.
• Fix: Fixed TaskJugglerScheduler to correctly generate task absolute
  paths for PostgreSQL DB.
• New: Repository.path is now writable and sets the correct path
  (linux_path, windows_path, or osx_path) according to the current
  system.
• New: Setting either of the Repository.path,
  Repository.linux_path, Repository.windows_path,
  Repository.osx_path attributes will update the related environment
  variable if the system and attribute are matching to each other, setting the
  linux_path on Linux or setting the windows_path on Windows or setting
  the osx_path on OSX will update the environment variable.
• New: Added Task.good attribute to easily connect tasks to Goods.
• New: Added new methods to Repository to help managing paths:

  • Repository.find_repo() to find a repo from a given path. This is a
    class method so it can be directly used with the Repository class.

  • Repository.to_os_independent_path() to convert the given path to a OS
    independent path which uses environment variables. Again this is a class
    method too so it can be directly used with the Repository class.

  • Repository.env_var a new property that returns the related environment
    variable name of a repo instance. This is an instance property::

    # with default settings
    repo  = Repository(...)
    repo.env_var  # should print something like "REPO131" which will be used
                  # in paths as "$REPO131"

• Fix: Fixed User.company_role attribute which is a relationship to
  the ClienUser to cascade all, delete-orphan to prevent
  AssertionErrors when a Client instance is removed from the User.companies
  collection.
