Add link to Flight components list

[Flight components list](http://flight-components.jit.su)

I know that the idea is to have a list of all the components integrated into the new website, but at the moment we don't have any place to show the growing list of Flight components. 

This is a simple site that gets a list of all Bower components and the filters them to only show the ones starting with "flight-". I know that it still has a LOT of room for improvement, like caching the request to Bower instead of doing it on every page load.
