Sentry should work now

BUT!

The code in bootstrap.php on line 61
````php
Sentry::instance();
````

Should not be there... but due to a bug in the `autoloader` of Fuel, this is the fix for now... Also due to that bug I noticed that the Log package was initialized twice... causing the handlers to be buggy. I added this inside the `_init` function, all the way on the top:

````php
/**
  * Initialize the class
  */
public static function _init()
{
  if(!is_null(static::$monolog)) {
    return;
}
````

You have to add that manually for now, since the Log package is a submodule. I already posted a bug on that repo...
