openruko keys:add fails, when following the README

[alanjds]

If you follow the README carefully, you cannot deploy. The user openruko@openruko.com is not created by default, and README dont inform this. Looks like you need to manually create an user after vagrant up. This pull-request fixes the README.

In fact, after you create the user you still stuck at openruko key:add:

vagrant@precise64:~/myapp$ ~/openruko/client/openruko keys:add
Enter your Heroku credentials.
Email: openruko@openruko.com
Password (typing will be hidden):
Found existing public key: /home/vagrant/.ssh/id_rsa.pub
Uploading SSH public key /home/vagrant/.ssh/id_rsa.pub... failed
 !    Heroku client internal error.

Is there something wrong with what I had done following the README?
