remove obsolete global let macro
[BUG #6849] add zip files for website modules distribution
[BUG #7633] removed outdated remarks about qxoo-build and qxoo-noopt
[BUG #7651] add images/desc attribute
[BUG #7182] implemented '@lint ignoreJsdocKey()'

- logging of jsdoc errors is now done in jshint.py
- so that it is possible to check e.g. unknown @hints against preceding
  @lint ignoreJsdocKey() entries up the hints tree
- Comment.py could be freed again from all console logging (!?)
[BUG #7182] applied '@lint ignoreJsdocKey' to Sinon.js

- and re-enabled lint/warn-unknown-jsdoc-keys for the framework 'api' job
minor comment
[BUG #7631] improved workaround
Added how to update the jsFiddle libraries to the tech manual.
fix API docs
[BUG #7661] add overrideMimeType XHR support
re-wrote minor part of CodeGenerator to work with pipelines
reverted the second pipeline to the much smaller nested calls

- interesting (but ugly) how you need to do all sorts of higher-order
  function constructions ("bind(bind...", "curry2(apply...")
- to capture various inputs and shuffle them into the right places for the
  consuming functions
