Add Cake aliases to manage Git remotes

Aliases that likely would be useful:

• List existing remotes
• Check if a remote exist by name
• Check if a remote exist by url
• Add a new remote
• Update an existing remote
• Remove an existing remote
• Rename an existing remote

Hi,

I've opened a PR that should cover the first two points, see #192 (I opened that PR before I saw this issue).

However, the build on macOS is failing for reasons that seem unrelated to my change. Any hints about what the problem could be would be appreciated.
