FormBuilder::checkbox can't be checked without session

If the value of FormBuilder::session is null, it’s not possible to set
a checkbox to checked.
Test checkbox without session.
Stashing limit/offset query values before performing total pagination count

Some database engines return zero, when using the count aggregate on a query with limit and offset. Just followed the same pattern for stashing the 'orders' clause before performing a count on the query, and adding back to the query when done.
Pivot updates recorded only if something updated
Fix associate on MorphTo

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.
