Title: Display illusionist output on compile error

When `illusionist` is not able to compile the file, we should output an error message to the user (like `sass` does it with sprockets).

The error message is not very useful right now (something that @charlesdemers might improve :smile:), but it’s useful to notify the user that something is wrong rather than failing silently.
