Added ability to pass parameters to rules

Hi @daylerees, I'm sending this PR to add a new functionality to this amazing package. Hope you appreciate. This PR adds ability to pass parameters to sanitizers rules and also fix temporarily issue #3. 

### Example of usage
Creating a rule class
```php
<?php
namespace Sanitizers;

class Suffix
{
	static public function sanitize($value, $suffix = '')
	{
		return $value . ' ' .  $suffix;
	}
}
```

Creating a route to test the new functionality

```php
Route::get('/sanitize', function(){
	
	Sanitizer::register('prefix', function ($value, $prefix = null) {
	    return $prefix . ' ' . $value;
	});
	Sanitizer::register('suffix', 'Sanitizers\Suffix@sanitize');

	// Construct rules array.
	$rules = [
		'*' => 'trim',
	    'name'      => 'prefix:Mr.|suffix:Senior',
	    'email'     => 'strtolower',
	    'code'      => 'str_pad:10,0,0'
	];

	// Data array to be sanitized.
	$data = [
	    'name' => 'Dayle   ',
	    'email' => '    me@DAYLEREES.com',
	    'code' => '  2435  '
	];

	$sanitizedData = Sanitizer::sanitize($rules, $data);

	dd($sanitizedData);

});
```

Output
```php
array (size=3)
  'name' => string 'Mr. Dayle Senior' (length=16)
  'email' => string 'me@daylerees.com' (length=16)
  'code' => string '0000002435' (length=10)
```
