7.0.0

New features:

• APIRequestUnauthorized is broadcast if requests repeated after a 401 resolution still return a 401
• $cancel now halts the HTTP request itself, and doesn't reject the main promise by default
• keyName method allows customization of the authorization header name

Additional breaking changes/notes:

• If a repeated request after a 401 resolution still returns a 401, any other requests in the repeat queue are silently canceled
• $cancel no longer rejects the main promise by default, but can be instructed to do so by passing the reject parameter
• The authorization header has been renamed from AUTHORIZATION to Authorization. Since HTTP headers are supposed to be case-insensitive this shouldn't be breaking, but in case you were referencing it explicitly in case-sensitive JavaScript, you can use keyName to change it back.
