Updated the isCoards script to return the error status to the shell

scripts/isCoards
- Routine &analyzeResults returns the # of lines of the @bad array
  as the status, or 0 if no errors are found.
- Use a "never-nest" style in routine "main", to move the error check
  to the top of the routine and avoid the else block
- Consolidate the main() and exit($?) statements
