Wiki pages for add-ons, templates, etc.

[Kurt G. | @kgriffs]

Hi everyone, just a quick reminder re our wiki (see also https://github.com/falconry/falcon/wiki). This is a great way to learn about who's using the framework, and to discover some of the handy add-ons, packages, and templates available for your projects.

If you haven't had the chance yet, please take a look and help us flesh out these pages. 

Thanks!
