changed few options in composer.json / moved the Seeds fldr  / added sentry install 

' added "illuminate/support": "4.0.x", to the composer.json
'added "src/Seeds" to the autoload/classmap clause
'moved Seeds to same tree level as migration
'added $this->call('migrate', array('--package' => 'cartalyst/sentry')); to ModelTestCase.php

still few errors in testing, investigating.
