Removed useless version marks from the xml configuration. Added DCMD profile configuration to install and delete profiles in a fermenter. Removed the old profiles configuration. Removed useless xml configuration error check because none has been triggered in five years, Removed several obsolete upgrade functions. Updated the web liveview.
