Title: Add Git::PurePerl::Util

Add a few utility methods that people who work with Git repositories will likely find helpful.

* `is_git_dir( $dir )` : determines if `$dir` is a `gitdir`
* `find_git_dir( $dir )` : Walks up directory tree trying to find a `gitdir`
* `current_git_dir()` : Find a Git repo somewhere above `$CWD`
