Title: Remove use of the `use` in closure

See https://github.com/fabpot/Pimple/blob/master/lib/Pimple.php#L81 :
Pimple give to the closure (as first argument) the container/application,
so we do not need to use `use($app)`.

Note :

* I did not test on php 5.4. But tests are OK on 5.3
* I think it is cleaner to use php default arguments than the use of `use`
* I fixed the CS : `function()` -> `function ()` (added a space before `(`)
