Several huge improvements


* Removed bundled Doctrine (which was pretty old)
* Added Composer, so this package can be easily installed
* Changed file locations and namespaces (now it's `\Fuel\Doctrine` which I think it's much better)
* Improved Logger class, now it works correctly with specific data types like DateTime and Objects
* Extended configuration options so it uses Fuel `db.php` and also supports all options. (no need to manage 2 files for database settings)
* Database options are very customizable. With inheritance. (even more powerful than Fuel offers)
* Removed `doctrine2.php` as this config isn't needed anymore since everything is in `db.php`
* Removed `phpquickprofiler.php ` because it's not required. All queries are correctly shown with proper EXPLAIN detals
* Improved README with detailed description and configuration information.
* Maybe more...

Tested with newest FuelPHP 1.6/develop and works perfectly :)

Also consider adding this package to Composer package list https://packagist.org/

It has never been so simple to add Doctrine to FuelPHP: `composer install` is all that's required and start using it immediately `\Fuel\Doctrine::manager();`
