Todo

Fix images in questionnaire config to not use an abslute path, using a placeholder variable in the text (compatible with translation).
Maybe find another way to include image than the plain HTML in config file and translation.
Show result value indicator.
Take out some logic from controllers.
Use service providers for most stuff in app/bootstrap.php.
Peers:
- externalize YAML parsing in QuestionnairePeer,
- factorize peers to be injected as shared services.
Maybe find a way to factorize site title and other variables, for example using a Makefile to convert .dist files, like README.md.dist with %title% replaced with real variable during make process in target README.md.
Not tested, but I guess the local server shown in readme may not work, as it don't rewrite URL's with Apache config override (.htaccess), and the website currently don't work with /index.php/* links.
Make the .svnignore work, or any way to ignore any directory and its content.
