Rename Void to Void_ since it is a reserved keyword in PHP7.1

[hboomsma]

Fixing the followint failure:

1) phpDocumentor\Reflection\TypeResolverTest::testResolvingKeywords with
data set #15 ('void', 'phpDocumentor\Reflection\Types\Void')
PHPUnit_Framework_Exception: Argument #1 (No Value) of
PHPUnit_Framework_Assert::assertInstanceOf() must be a class or
interface name

This is a BC break
phpDocumentor/ReflectionDocBlock#75 updated phpDocumentor/ReflectionDocBlock accordingly. If other packages need an update too, please let me know, I'm happy to help.

Hi @hboomsma,

Thank you for your contribution; it is awesome to see that people use this library even in really up to date versions of PHP (or preparing for it) and it is even more awesome to see contributions like these to help ensure this works.

I have just merged the pull request and tagged a new version of the library
