Multi Git Status Versions Save

This release adds detection of unsafe repos and skips them.

In april 2022 a vulnerability was found in git. See https://github.blog/2022-04-12-git-security-vulnerability-announced/. The implemented fix for git is to warn the user and to skip the repo. The warning screws up our output, so we also detect and skip those repos with our own message.

This release adds the --flatten option, which shows only one status per line. If a repo has multiple statuses, one line is printed per status. This is helpful when used in combination with grep or sort.

This is a major release that breaks backwards compatibility with v1.0.

This release includes the following changes:

• An installer script (install.sh) is now included.
• You can now specify multiple directories to process
• The depth is now specified using -d or --depth instead of adding DEPTH after the directory. This breaks backwards compatibility.
• Various documentation and man page corrections.

Initial stable release.
