Progress towards better#53

config.sh is not config in letsencrypt.sh

Now removing working copies after repositories have been initialised. Also cleaning up working copy directories during initial cleanup on reinstalls in case the installation failed to complete.

Extended the initial cleanup to include possibly left-behind ssh-related bits from a failed installation.

Now setting up the repositories with a master branch and a placeholder file so they’re ready for use by the Builder script.

Escaped the letsencrypt.sh configuration template substitution values for sed. Added log statements for progress indication.

Jumping sudo -i mode for commands that require pipes. Fixed the route for the Let’s Encrypt challenge.
