Working to get installation working smootly.
* Pivip_Controller_Module_Abstract now has a _refresh() method that can redirect the user to the current page and display a message.
* Pivip_Utility_Abstract and Pivip_Utility_Doctrine created, which are - you guessed it - utility classes.
* Pivip_Module_Abstract's bootstrap() method no longer is static. It wasn't really needed since Pivip_Modules returned an instance anyway, and now you can refer to the non-static methods in bootstrap().
* [Admin] A menu link is added during installation
* [Install] Installation is now commenced when the database has not been configured yet.
* [Openid] When Install has finished its installation, the superuser will be asked for and saved to the database.
