more forgiving normalization

Any reason not to merge this in?

The only one being that the weblinter would then view such options as valid even though the rest of Travis doesn't.

[joshk]

I'm a little confused then. Can you give me an example of what is valid on Travis and what this PR would regard as valid?

deploy:
  provider: heorku
  on:
    node_js: 0.10
addons:
  coverty_scan:
    project: example

The above is valid with this PR, but would not be accepted by travis-build. Loading it through travis-yaml would fix that.
