Wrong order of config/autoload

Configuration must load in that order:

 * global.php
 * \*.global.php
 * local.php
 * \*.local.php

But in fact, it is not. I am create gist, to prove it https://gist.github.com/ftdebugger/5934533. Here the result:

```
Array
(
    [0] => config/autoload/global.php
    [1] => config/autoload/local.php
    [2] => config/autoload/some.global.php
    [3] => config/autoload/some.local.php
)
```

Loading configuration in two steps guaranteed needed order
