- added missing quit command to global help topics - added hint about help [topic] - let x11runas determine the DISPLAY itself by using MCORE_XORG_DISPLAY - added no_duplicate() function for internal use - let require() and provide() check for duplicate items via no_duplicate() - added verify_requirements to be able to resolve missing plugin requirements - mecho() and eecho() should honor the '-n' echo option - added path_not_empty() functions which is used by helper_graphic_rebuild_xorg_conf_d() of the graphic plugin
