GitHub rate limit when publishing from shared IP

[gampleman]

Today I tried to publish my first package. Here's what happened:

$ elm-package publish
Verifying gampleman/elm-visualization 1.0.0 ...
This package has never been published before. Here's how things work:

  * Versions all have exactly three parts: MAJOR.MINOR.PATCH

  * All packages start with initial version 1.0.0

  * Versions are incremented based on how the API changes:

        PATCH - the API is the same, no risk of breaking code
        MINOR - values have been added, existing values are unchanged
        MAJOR - existing values have been changed or removed

  * I will bump versions for you, automatically enforcing these rules

The version number in elm-package.json is correct so you are all set!
Error: The following HTTP request failed.
<https://api.github.com/repos/gampleman/elm-visualization/tags>

{"message":"API rate limit exceeded for 87.246.78.46. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)","documentation_url":"https://developer.github.com/v3/#rate-limiting"}

I haven't been doing anything much with Github, except fairly normal usage, so I suspect it might have to do with shared IP addresses (although that's just my guess).

This repeated for a couple of hours until finally I managed to publish my package.

I was wondering if we could add a way to (optionally) authenticate the requests, so that the process could be unblocked.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.
