author landing page: (edit: ticket now about upgrades)

[mpdehaan]

the work of an author can span repos or even organizations

to better extend the ability of SourceOptics to show a person's contributions, when we click on an author in either the repo stats or the commit feed, we should not go to see their commits across all repos (or their stats across repos), we should go to a landing page for that author

it should show these things:

a link to all author repo stats (or embedded into the page, which is better)
a link to all author commits in a unified feed - this should still be a link
a link to the graphs for the author, preloaded to the repos they have committed to in the interval

[mpdehaan]

this is now available in that it shows the links for each author.

It can still show some summary stats in a table across all repos.

We should also add some FontAwesome icons to the links.
