Instead of using the same logger for all the things
which makes it incredibly hard to figure out what the images
and there builds are doing; instead have it so that each
image gets its own logger which is then used by tasks that
process that image.
Each images logs now will (optionally) go to a logs directory
that can be more easily read and looked over and leaves
the main logger for informational/task kind of
output only.
