Adds changelog entry
generalize work_package#preview into journals#preview

WorkPackages#preview was essentially two methods now. I could have changed that by splitting it up into #preview and #journal_preview but other journals might need previewing, too.
indentation fixes
cleanup work_package#quoted
removes unsupported format
removes hard dependency on work_packages from journals_helper
replaces issues controller links on my page
uses work_packages_controller for action menu

It was not yet possible to replace bulk_edit as the controller does not yet provide such an action
