Implement cancel of chown of many files.

Browse Source 
Implement error message with follow buttons:
"Ignore" -- ignore current error;
"Ignore all" -- ignore current error, try chown of other selected files,
and ignore all following errors;
"Retry" -- retry chown operation;
"Cancel" -- cancel chown operation immediately.
