Allow any 'callable' action, not just anonymous functions

If creating routes dynamically, like the following:

```php
$router->getRoutes()->add(new Route(array('GET'), '/foo', array($this, 'xxx')));
```

... then the previous code will fail because `php array($this, 'xxx')` is not an instance of Closure, however `is_callable` will work just fine.

Make Paginator::getUrl have priority over appends
Fix many to many polymorphic pivot updates

`$morphType ` set by `setMorphType` is being included in queries from x->pivot->save() and the like. As the object is being added as a public data member on an object with an empty original, it is treated as an attribute and added as a column to the queries. As this column doesn't exist, the query will be erroneous.
