Semicolon Fixers

Replaces #511.
And as I said - it will works like a charm.

Your testcase:
```php
<?php

$this
    ->example()

    ;
```

after : `php php-cs-fixer fix 1 --fixers=spaces_before_semicolon,multiline_spaces_before_semicolon` (on in reverted order):
```php
<?php

$this
    ->example();
```
