64 - Simplifying the hidden stuff

Thankfully most of our users don’t need to be exposed to the complexity that sits beneath the surface. Nevertheless, the more complex the base, the harder it is to iterate and improve the visible stuff. Building on releases 62 and 63, this release simplifies the way Concentric runs, moving to more industry-standard tools. Going forward we should therefore be able to spend more time doing stuff that noticeably improves the Concentric experience.
