Moving all influencers to a separate tab

As requested, I split out the influencers from the rest of the links. Thought in our case a separate tab will be easier to maintain than a whole page, since if we're not using Jekyll, including common code snippets would be a pain.

If the content keeps growing, we might need to think of a proper CMS.

Also, since I'm moving a large chunk of code anyway, I sorted the names of influencers.
