I thought I had committed this already. Since appliances/images may be
distributed, we should have bindist set. It only took me nearly 5 years to
fix this bug.
Instead of having everything in the root directory, split them in seperate
directories (appliances, scripts, & configs). This makes things a little
tidier.
Also added a now Makefile target, appliance-list, that prints a list of the
available appliances. The split directory change made this easier.
