Finally fixed trucation count issue.

Was counting empty lines from the file.
Added commit links to byline.

Inadvertently fixed a bug on article page while at it.
Adjusted truncations for correct rendering.
Updated JS dependencies.
Updated banner copy and layout.
Tested for some strict PHP notifices.
Deleted some old junk.
Made GitHub queries client-side.

This attended a move to hosting on Heroku, required an updated version
of jQuery, and prompted a new, sad "edition."
