cap-ec2 works for capistrano 3.2.1, but not >= 3.3.3

[lucaslward]

When I upgraded to the latest capistrano, I now get the following error:

cap production ec2:status --trace                                                                                                                                                                                                                                     !8848

I believe this is caused by the following commit in capistrano:

https://github.com/capistrano/capistrano/commit/5bae7fb40ca59d60a859400ec52c709c7686c387

The available_roles method was removed. I think it's because there's a new concept of 'filters' in 3.3.x

Duplicate of #34?

[andytinycat]

Can you try with 0.0.18 and let me know if that fixes it for you?

[ustuehler]

Yes it does. Issue #39 remains, however. :)

Thanks to @freakphp, you should be all good now. Thanks for your patience!
