[#DCOM-164] ignoring @type phpdoc annotations

[Issue DCOM-164](http://www.doctrine-project.org/jira/browse/DCOM-164)

> phpDocumentor guys wrote their own PSR to define how to use phpdoc properly (https://github.com/phpDocumentor/phpDocumentor2/blob/develop/docs/PSR.md).
They deprecate the @var annotation and recommend using @type instead.
>
> The @type (phpdoc) annotation is not blacklisted/ignored by the AnnotationReader. Code that uses this annotation raises errors with Doctrine/Annotations.
>
> @type should be blacklisted/ignored, but may that create BC breaks for users?
