Title: Avoiding dead threads and a little bit improvement for growl notifier

Hello! I want to include functionality of your gem in mine https://github.com/ruby-talks/talks, so I started to play with it and want to improve a little bit what I think will be more comfortable in usage.

1. When you send to notify method not enough options for notifier it will throw you an error because `option[:some_option]` will return `nil` and `system('bla', 'bla', nil)` will return type error. So I just add `.to_s` for each option call.

2. It will be nice that if all notifiers can just get message in notify method and show it without other options and without hash-style method call. So now we can write `Notifier.notify 'bla bla'` and if you use Growl on your machine it will show you simple notification.

Thanks! :)
