Give relevance to REQUEST_URI over PATH_INFO

I recenlty installed AnchorCMS on my localhost `XAMPP Ubuntu 12.04.2` and after the installation every route goes to the homepage, after checking around I've seen that (in the nano framework) we give prefference to `$_SERVER['PATH_INFO']` over `$_SERVER['REQUEST_URI']`, I changed to the actual one of the commit and now it seems to work fine.

Sorry my bad english :)
