Bug: Lever position ifcheck doesn't work properly
Danger: Low - State of functional levers, pullchains, switches, and buttons can't be checked

mud_prog.c, mprog_do_ifcheck

Locate:

      if( !str_cmp( chck, "leverpos" ) )
      {
         int isup = FALSE, wantsup = FALSE;
         if( chkobj->item_type != ITEM_SWITCH || chkobj->item_type != ITEM_LEVER || chkobj->item_type != ITEM_PULLCHAIN )
            return FALSE;

         if( IS_SET( obj->value[0], TRIG_UP ) )
            isup = TRUE;
         if( !str_cmp( rval, "up" ) )
            wantsup = TRUE;
         return mprog_veval( wantsup, opr, isup, mob );
      }

Change to:

      if( !str_cmp( chck, "leverpos" ) )
      {
         int isup = FALSE, wantsup = FALSE;

         if( chkobj->item_type != ITEM_SWITCH && chkobj->item_type != ITEM_LEVER && chkobj->item_type != ITEM_PULLCHAIN && chkobj->item_type != ITEM_BUTTON )
            return FALSE;

         if( IS_SET( obj->value[0], TRIG_UP ) )
            isup = TRUE;
         if( !str_cmp( rval, "up" ) )
            wantsup = TRUE;

         return mprog_veval( wantsup, opr, isup, mob );
      }

This ifcheck should only let 4 items times get passed it, so it needs to do an AND comparison. Not an OR comparison. Otherwise the check is somewhat useless.
