Title: Changed environment config loading from array_merge() to array_replace_recursive()

Small change when loading environment specific configurations. Now the code below will merge the username/password into database connections array instead of replacing it entirely.

~~~php
array(
'mysql' => array(
'username' => 'myname',
'password' => 'mypass',
),
),
);
~~~
