Feature/add inline encryption

[vvucetic]

This PR is for supporting inline encryption supported from Ansible 2.3
I tried to not refactor too much, but that would produce some duplications and nasty code so, a bit more of refactoring. I might have missed something, so review is very welcomed.

Nice feature, waiting for it to be merged :)

I was tired of waiting for the merge of this new feature and I tried it in local. Unfortunately, in my machine with archlinux and lxde it does not work properly. When encrypting a single variable, it append a "\c" character at the end of the password that produces a wrong result. When you decrypt, this character appears. I am not a developer and I am not able to correct the code, sorry. Of course, it could be possible that I did something wrong.

I'll try to fix that. I'm on macOs and haven't noticed that, but I'll try to make it work for all platforms.

@dbseoane can you please try again?

Wonderful @vvucetic. I just tried it and it works perfectly.
In fact, it works better than the atom plugin ;).
Thank you very much.
