DI compilation fails on class keyword

[shanethehat]

PHP 5.5 introduced the ability to use the class keyword to return the fully qualified class name of a class: http://php.net/manual/en/language.oop5.basic.php#language.oop5.basic.class.class

When compiling the DI container, the setup module's PHPScanner tokenises PHP files that it finds, and upon discovering a T_CLASS token it attempts to capture the following class name and create a ReflectionClass object from it. In the case of Foo::class this fails, causing a reflection exception.

The PHPScanner needs to be modified so that it allows for this use of the class keyword.

This should be fixed now.
