Location of recipes needs snippets prefix to path in README.markdown (but I found it eventually)

[therobyouknow]

In the README.markdown section on https://github.com/disqus/DISQUS-API-Recipes the documentation refers to code for example: /php/get-thread-details.php

But is is not clear where in the repository this actually is: there's no php directory shown in the view of the repo on the same page above the README.markdown.

Fortunately I figured out where this is by searching in google for one of the files. The location of the examples is: https://github.com/disqus/DISQUS-API-Recipes/tree/master/snippets/php

Please update the documentation with this snippets prefix. Thanks.

Good opportunity for the repo to switch over using local variables for the docs so we can future-proof these kind of shenanigans.
