Indent validation messages with null clip names in output.
modified code indentation
All validation outputs remove duplicate clipnames in output and adds indentation to output.
Correct indentations
Changed padding to make the validation messages more evenly spaced.  Made clip names their own lines.
Removed ':' after clip name.  No longer needed as it has its own line now.
