Clarified space parameters for contacts and added missing ones. List of changes: -Add contact bias to space parameters -Add solver iterations to space parameters, instead of a specific physics server function -Renamed BODY_MAX_ALLOWED_PENETRATION to CONTACT_MAX_ALLOWED_PENETRATION to make it consistent with other contact parameters
