Split up Issue objects

This creates 3 classes; one for iterations (Short), one for direct GETs
(Issue), and one for events (EventIssue). Most attributes
are directly assigned, except where otherwise commented.

Some cassettes needed to be updated for the relatively new 'assignees'
attribute that now comes back. A sample json needed to be updated as
well. Cassettes that needed updated that were associated with
authenticated calls got the calls updated to use auto_login as well.

Some cassettes will break between older requests and newer, so tag those
tests accordingly. Allow the tests to work in older requests land for
now.

The search tests needed to be updated as well, label name changed and
syntax changed slightly.

Update AUTHORS.rst

Adding name to contributors list per contributor guidelines

Implement PullRequest refactor

Add "assignees" option to create_issue

There was not an integration test for this code path. Testing this path
uncovered a bug in ShortUser when attempting to repr such objects. The
name attribute is not available in the short object, so that object
should print differently.

The argument order for create_issue in github.py needed to match that of
create_issue in repo.py, since it just passes through to that function.

This commit attempts to add support for multiple assignees issue creation.

This creates 3 classes; one for iterations (Short), one for direct GETs
(PullRequest), and one for events (EventPullRequest). Most attributes
are directly assigned, except where otherwise commented.

A couple cassettes needed to be updated, and the sample json for
pull_request needed to be updated as well. Updating that one required
updating the tests for the now current data.

Switch class used when creating a user

create_user fails because the github3.users.User class expects data that is not present at the time of user creation. github3.users.ShortUser needs to be used instead.

Implement Organization object refactor

This creates 3 new objects, one for iterations (Short), one for direct
GETs (Organization), and one for events (EventOrganization). Most
attributes can now be directly assigned, aside from a few that are only
returned in the API if they are set on the server. Default those to
None.

Many test cassettes needed to be updated to pick up attributes added to
orgs since the cassette was recorded (yay for additive REST APIs...).

Introduce a 'auto_login' method to handle either token auth or
username/password auth. Use it in the places I needed to update the
cassette.

Fix a few POST calls that were sending malformed (according to GitHub
API) json data. Specifically an empty permission is not accepted.

Jesse and I are working on making the internals somewhat simpler and the
API more descriptive. This brings the Projects API Support in-line with
that effort.

The Projects API allows a user to fetch a project card directly,
without reference to an organisation or repository. This commit
exposes this ability by adding a `project_card()` method to the
`GitHub` class.

Callers may obtain any project card to which they have access by
calling this method directly:

    import github3
    card = github3.login(token='token').project_card(1234)

The Projects API allows a user to fetch a project column directly,
without reference to an organisation or repository. This commit
exposes this ability by adding a `project_column()` method to the
`GitHub` class.

Callers may obtain any project column to which they have access by
calling this method directly:

    import github3
    column = github3.login(token='token').project_column(1234)

Drop preview header from reviews API call

Use correct attribute for pull request review ts

Add exception to indicate an incomplete data set

This communicates far more clearly to the user what may have happened to
cause issues with the response they were expecting. In the case of the
issue raised, this points people towards the token they may be using and
its scopes.

Closes #693

As of
https://developer.github.com/changes/2017-05-09-end-black-cat-preview/


the reviews endpoint is no longer preview, and is now an official part
of the API. It is no longer necessary to set a header when accessing
this endpoint.
