my-repo-pin: bump to 0.2

Changelog:

- Add the my-repo-pins-max-depth customization variable. This variable
  prevents my repo pins from accidentally recursing too far in the
  code-root directory. Solves a performance issue with git subtrees.
- When cloning a project from a fullly qualified URL, we make sure the
  project does not exists locally first. If it does, we jump to the
  local clone without trying to clone it again.
