server + browser side: blogging refactoring (draft), huge commit sorry: /!\ everything is not working yet, group blog is not working for now - adaptation to backend changes - frontend commons part of blog have been moved to QuickFrontend - (editors) button "WYSIWYG edition" renamed to "preview" - (editors) Shift + [ENTER] is now used to send a text message, [ENTER] to finish a ligne normally - (editors) fixed modifiers handling - global simplification, resulting of the refactoring - with backend refactoring, we are now using PEP again, XEP-0277 compatibility is restored \o/
