Shawn Neal 643f2f9eab Add --max-issues argument to limit requests
This addresses issue 71 by providing a configurable limit on the number of issues to retrieve. By default this limits the number of issues to 500 which should help users stay under the GitHub API limit and keep change logs from growing ridiculous in size for older repos.
