Add 'git-repo-list' at .gitignore

'git-repo-list' is generated by 'listing.all.repos.from' script and contians list of all git repositories from subdirectories of specified directory.
Priotize top risky items among all repositories.

You can use, just, 'run.batch.at' script at the top of target project. It'll scan all repositories and run 'churn.ccn.analyzer.pl' script onto each git repository internally. And it'll gather all 'file_churn_complexity.csv' and sorted by churn (commits) and file complexity descending order. Finally it'll export top risky items to be reviewed or refactored to 'top_risk_files.csv'.
