HTML formatting: TWO fixes in one! Fixed a bug introduced in 2.3.0-beta: the stylesheet cannot be defined within the email templates (aka ActionEmail) anymore. Instead, a default (ready for use) stylesheet is provided into /css/email.css and it can be overriden by the configuration parameter email_css. The fix consists in transforming the stylesheet into inline style... which fixes a limitation of gmail and Outlook that support only the inline styles. The implementation relies on a new library: emogrifier. This library has been changed (home-made utility) to be compatible with PHP 5.3 (declaration of arrays).
