v1.3.0

This release introduces a PHP version bump. doctrine/annotations now requires PHP
5.6 or later to be installed.

A series of additional improvements have been introduced:

• support for PHP 7 "grouped use statements"
• support for ignoring entire namespace names
  via Doctrine\Common\Annotations\AnnotationReader::addGlobalIgnoredNamespace() and
  Doctrine\Common\Annotations\DocParser::setIgnoredAnnotationNamespaces(). This will
  allow you to ignore annotations from namespaces that you cannot autoload
• testing all parent classes and interfaces when checking if the annotation cache
  in the CachedReader is fresh
• simplifying the cache keys used by the CachedReader: keys are no longer artificially
  namespaced, since Doctrine\Common\Cache already supports that
• corrected parsing of multibyte strings when mbstring.func_overload is enabled
• corrected parsing of annotations when "\t" is put before the first annotation
  in a docblock
• allow skipping non-imported annotations when a custom DocParser is passed to
  the AnnotationReader constructor
