Added NoLineAfterPhpdoc Fixer

Say hello to another fixer. :)

TODO:
* [ ] Add tests including properties
* [ ] Add tests including constants
* [ ] Add tests including variables
* [ ] 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. :)
Just tried to. It doesn't work? The readme test passes on travis too?
