This is required for non-owners to create organization repos on github.

The input and response types for commit messages differ in the API.
While commit.Tree and commit.Parents are objects with fields when
returned by the GitHub API, the attributes are plain strings when
creating new commits.

See: https://developer.github.com/v3/git/commits/#create-a-commit

The GitHub API supports a "content" attribute when creating a new tree
[1], which allows to skip additional requests to create blobs first.

First draft, suggestions for improvements are welcome. The snippet
should serve as the idiomatic guide on how to get all pages for a given
resource (a common use case without an obvious solution, hence the docs
can be very helpful).

Includes additions to User, Organization, Repository, and Gist.  Some
minor changes to existing fields based on changes in the v3 API (for
example, Gist.User became Gist.Owner).  Most everything else is new
additions.

refs #103

This includes all of the methods mentioned in this blog post:
https://developer.github.com/changes/2014-03-18-paginating-method-changes/
as well as a handful of others I found.  Sadly, this is a breaking
change for many of these methods because it changes the method
signature, but with yesterday's API change these methods are now broken
anyway. :(

it's not the cleanest, but it works.

instead of inspecting the JSON tags on the struct fields directly,
actually run it through JSON marshalling and unmarshalling, then compare
those results.

- ListCodeFrequency
- ListPunchCard

- use Timestamp for Week fields instead of int
- rename WeekHash to WeekStats

So it appears GitHub already supports multiple types of subscriptions:
repositories and threads.  I'm leaving the data type simply as
'Subscription', but am updating the method names to avoid confusion,
since they're both part of the ActivitiesService.

mark RateLimit method as deprecated in favor of RateLimits which returns
both the core and search limits. (see deprecation notice in API docs:
https://developer.github.com/v3/rate_limit/#deprecation-notice)

depending on who people are using rate.Reset this may or may not be a
breaking change, since Timestamp supports all of the exported methods
from time.Time.

this is a breaking change, but this was only recently added so I'm not
too worried.  This also seems the best way to handle sub-namespaces on
this method.

Includes basic CRUD methods on repositories as well as listing branches
and tags.

- Repositories.Delete
- Repositories.ListTeams
- Repositories.ListTags
- Repositories.GetBranch

I changed my mind.  This really is terribly verbose, and looking at the
design of the API, it seems unlikely GitHub would change the
subscriptions endpoint to include anything other that repositories.  And
if they do...  well, we'll deal with it.
