    [MCHECKSTYLE-389] Partial revert of MCHECKSTYLE-365 severity change back to 
'null' default
    
    The severity setting even on original logic is incorrect.  It must remain 
null if it is to work properly at all.  While counts in fact are off, the 
entire section will be lost if it doesn't contain issues in at least 'error' 
due to the change when using default configurations.  This has to be reverted 
as not originally fixed properly so that the rules aggregate will display.  
Example case has no 'error' type, only 'warning'.  Changing this to 'warning' 
will pick that section up.  Usin [...]
