Add Python and PHP code examples

[yadutaf]

This is a first PR from this week's Hackathon. This PR adds code generation, based on what's done on https://api.ovh.com/console with a couple of nice additions:

• It generates valid code (Yes, that's a feature, hum, hum)
• It supports arbitrarily nested structures
• It brings syntax highlighting, making the current production code look... terribly old
• It only generates required arguments
• It supports all json types (lists will be in a future PR to keep things clean)

I'm definitively NOT a js developer. Although I'd be glad if this PR is accepted as-is, I'd be even happier with an in-depth review, especially regarding modules organization and lib vendoring.

If you want to get a glimpse on the futures changes, you may have a look at https://github.com/yadutaf/ovh-api-console/tree/jt. In particular, I believe the next commit will be yadutaf@d246f8b. I feel quite comfortable about it and this is a necessary feature.
