v0.3.0

• Breaking changes
  • Defaults and schemas are now defined using a directive in the YAML configs instead of
    implicitly by looking at load paths. See (#7) for
    more information on migration;
• New features
  • $include and $schema directives are now available in config files, allowing users to
    validate and include defaults at any part of the config
    (#7);
  • A new $content_include directive allows users to include the content of a file as a YAML
    string (#8);
  • The _file_dir Liquid variable is now available in all included files, containing always the
    absolute path to the file being loaded (#7).
