* Code cleaning and fix some small errors using Phpstan * Configure pre-commit to run Phpstan before each commit * Some little improvments and logging, mail, smarty & URL libs * Add Sentry integration * Add Webstat JS code inclusion * Install Smarty dependency using composer Breaking changes: * Rename Event class as HookEvent to avoid conflict with PECL event * URL with refresh GET parameter now automatically trigger redirection without it after page loading to avoid to keep it in URL
