Closes #19.

If magit-standup-link-package is git-link, each commit links to its web page, for example on GitHub. Auto-detect checks for orgit, then org-git-link, then git-link.

• If git-link does not support the remote, the commit shows as plain text.
• The code turns off the kill ring, the browser, and the C-u prompt of git-link-commit.
• A local commit has no web page until you push it. The README says this.
• git-link finds the remote again for each commit, about 15 ms each. A faster way needs the private git-link functions, so the code does not use it.
