Subject: ci: speed up Travis

The new configuration only runs coverage checks against Node.js LTS,
which speeds up all the other test runs. By, like, a lot. Also, the
entire file has been extensively commented, so the next time we
need to mess with it, we'll be able to better remember why all the weird
bits are there.
