Make it easier when using salt-ssh

[remichristiaan]

Using the tplroot method (borrowed from the ufw-formula) prevents having to set --extra-filerefs when using the formula with salt-ssh.

I've only tested it on my own salt deployment which worked without a hitch.

I've added a fix for the sources list.

LGTM. Please confirm when re-tested successfully and I am happy to merge.
thanks @remichristiaan

Travis failed, seems not all packages are installed, complained about not having jinja/yaml.

See #182 ;-) . If you could test manually that would be appreciated.

Tested on my dev env with salt-ssh ... no problems observed.

Thanks @remichristiaan for this.

[remichristiaan]

I've ran more tests and there is a hitch ... need to add some code in other places too. Sorry, tomorrow I'll send in the right pull-request.

[noelmcloughlin]

No problem - I have reverted.
Unfortunately Travis is broken so extra pressure on PR submitter to ensure fixes work.
Send in a correct PR when you are ready.

@remichristiaan I'm aware that this PR has been reverted in #215. As a note, the canonical source to refer back to is https://github.com/saltstack-formulas/template-formula/blob/master/template/map.jinja. This has been crafted to work for salt-ssh as well. However, it will take some effort to apply here in this formula. In terms of Kitchen/Travis, it will be a lot easier if we apply the inspec-based testing from the template-formula as well. Again, this will take some time and effort.
