1.0.0-alpha1

This release contains numerous BC breaks from the 0.x series. Please note these breaks and refer to the upgrade guide.

• BREAK: Requires PHP 5.5.0 and greater.
• BREAK: All providers have been moved to separate repositories, one for each provider.
• BREAK: All public properties have been set as protected or private and getters/setters have been introduced for access to these properties.
• BREAK: The Provider\ProviderInterface has been removed. Please extend from and override Provider\AbstractProvider.
• BREAK: The Entity\User has been removed. Providers should implement the Provider\UserInterface and provide user functionality instead of expecting it in this base library.
• BREAK: The Grant\GrantInterface has been removed. Providers needing to provide a new grant type should extend from and override Grant\AbstractGrant.
• A generic Provider\StandardProvider has been introduced, which may be used as a client to integrate with most OAuth 2.0 compatible servers.
• A Grant\GrantFactory has been introduced as a means to register and retrieve singleton grants from a registry.
• Introduced traits for bearer and MAC authorization (Tool\BearerAuthorizationTrait and Tool\MacAuthorizationTrait), which providers may use to enable these header authorization types.
