Member tag ($s): Add deprecation warning (XH 1.8?)
Member XH\Controller::handlePagedataEditor (): Unused?
Member XH\Controller::handleSitemap (): Declare visibility.
Member XH\Controller::sendStandardHeaders (): Emit error message only in admin mode?
Member XH\Controller::setBackendF (): Handling of userfiles, images and downloads is probably not necessary, as this should already be handled by the filebrowser. Otherwise media had to be handled also.
Member XH\Controller::setFunctionsAsPermitted (): Rename!
Member XH\Controller::wantsEditContents (): Do we need $f == 'save' && !$download? IOW: isn't the script already exited in these cases?
Member XH\IntegratedPluginMenu::makeHelpItem (): target=_blank
Member XH\Mailform::process (): Remove static variable for better testability.
Member XH_createLanguageFile ($dst): Remove handling of LANGconfigs, unless they won't get reintroduced.
Member XH_decodeJson ($string): Deprecate starting with 1.8.
Member XH_encodeJson ($value): Deprecate starting with 1.8.
Member XH_helpIcon ($tooltip): Change the DIVs to SPANs and require the $tooltip to be an inline fragment (requires block level elements to be removed from all help texts–even $plugin_tx).
Member XH_lastJsonError (): Deprecate starting with 1.8.
Member XH_plugins ($admin=false): Might be optimized to set $admPlugins only when necessary.
Member XH_renameFile ($oldname, $newname): Deprecate for 1.8.
