Function type hints

[mgrip]

input:

function type_hinting_test(array $test, int $int_test, string $string_test = '') {
    return $int_test;
}

output:

function type_hinting_test($test, $int_test, $string_test = '') {
    return $int_test;
}

Mostly fixed in #35, but let's leave this issue open until support for array and callable are possible (glayzzle/php-parser#113)

There is also a problem with '?' (for nullable)
Input:

public function for(?User $user)
    {
        $this->user = $user;

        return $this;
    }

Output:

 public function for(User $user)
    {
        $this->user = $user;

        return $this;
    }
