Added NoLineAfterPhpdoc Fixer

Say hello to another fixer. :)

TODO:
* [ ] Add tests including properties
* [ ] Add tests including interfaces
* [ ] Add tests including traits

Note, these cases are already handled by my implementation, I think, so the tests should be a trivial addition. :)
I would make a getter for it with static property inside method, like in all other fixers, eg https://github.com/FriendsOfPHP/PHP-CS-Fixer/blob/master/Symfony/CS/Fixer/PSR2/BracesFixer.php#L482
