improved functionality, checking if notify-send command is available
- replaced shell_exec with a more robust Symfony\Component\Process\Process class
- tests failed if you run them on a non-ubuntu box
- tested on ubuntu 13.04 and mac osx 10.8.4
minor fixes:
- restored getEmailClient and setEmailClient in Namshi\Notificator\Notification\Handler\EmailVision.php
- Namshi\Notificator\Notification\Handler\NotifySend::handle returns the output
- removed blank line in Namshi\Notificator\Notification\Handler\NotifySend
- add phpdoc to Namshi\Notificator\Exception\ExecutableNotFoundException
