* Introduced --allimages and --images on the command line
tools. What was --images (which was a list of containers
or images) is now --scan|-s.
* In the client API, we still just have one scan_images but
it has an optional argument tha allows you to scan all or
not. The default is to not scan all (i.e. intermediate
images).
* ApplicationConfiguration also now has a variable for all
images and just images.
