v0.9.3  2018-11-01
    - Configuration validation is now using a JSON schema
      (try "qgoda schema").
    - Validator is Ajv (https://ajv.js.org/), JSON schema version
      "draft_07".  The validator is called with "coerceTypes" set
      to "array", and "useDefaults".  That means that a lone string
      value is automatically coerced into an array, where needed.
    - Replaced the underscore with a hyphen in all config variables,
      so that "exclude_watch" is now for example "exclude-watch".
    - New commands "qgoda schema", "qgoda javascript", and "qgoda js"
      (which is an alias for "qgoda javascript").
    - Gradually increasing test coverage (displayed on github page
      https://github.com/gflohr/qgoda).
	- The i18n seed repo is now the official one (not file:///...).
	- New date functions for W3C and RFC822 date and time formats
      (try asset.date.w3c, asset.date.rfc822, asset.date.w3cLocal,
      and asset.date.rfc822Local)
	- yeoman generator (work in progress), see
	  https://www.npmjs.com/package/generator-qgoda.
	- Plug-ins present in ./node_modules are automatically loaded.
	- Asset priority is now honored in all generation rounds.
    - Configuration variable "front_matter_placeholder" is now
      "front-matter-placeholder" and an object.  The keys are the
      chain name, and the value is the placeholder as a string.
	- The generator meta tag is now configurable in config.generator.
	- Added "Strip" to the default processor chains for discarding
	  leading and trailing whitespace from the generated files,
      useful for XML output.
	- A new "xml" processor chain, defaults to ['TT2', 'Strip']
	- Non-standard strftime extension '#%' for the ordinal day
	  of the month (1st in English, 2eme in French, 3. in German),
	  PRs for other languages are welcome.
	- New location placeholder "basename_nodate" which strips of
	  leading YYYY-MM-DD- from the basename for Jekyll migration
	- More documentation on http://www.qgoda.net/:
	  * Defaults
	  * Filters
	  * Multilanguage
	- About 30 % of the web site is translated to German.
	- Fixed issues:
	  * https://github.com/gflohr/qgoda/issues/32
