Defaults for multiples, intended behaviour

In V3 of the GitHub API, pull request comments are created in two ways. The
first way is to create a comment on a specific line of a file in a commit
with the following parameters:

| Name      | Type    | Description                                            |
|-----------|---------|--------------------------------------------------------|
| body      | string  | Required. The text of the comment                      |
| commit_id | string  | Required. The SHA of the commit to comment on.         |
| path      | string  | Required. The relative path of the file to comment on. |
| position  | integer | Required. The line index in the diff to comment on.    |

And the second way is through a reply to an existing comment with the following
parameters:

| Name        | Type    | Description                           |
|-------------|---------|---------------------------------------|
| body        | string  | Required. The text of the comment     |
| in_reply_to | integer | Required. The comment id to reply to. |

This commit adds support for the second (or "Alternative Input" according to
the GitHub docs) way.

This commit fixes a bug where if a multiple value argument (slice) has default
values, the submitted values will be appended to the default. Not
overriding them as expected.

[docs] Satisfied golint.

- SkipRouter should also be ErrRouterSkipped (or similar) but a change would break the public API.

[docs] Add http://www.gorillatoolkit.org/pkg/mux to README.

[refactor] Only wrap regexp in group if not already in a group + perf. gains.

Fixes #152.

Add tests for RateLimitError.

Refactor populateRate into a more general parseRate.

Rate is now a method, not a field.

Mention RateLimits rather than RateLimit since the latter is deprecated.

Use Go convention for marking deprecated identifiers. See
257114af91.
