Tonis Tiigi 01ba0a935b Add image store
The image store abstracts image handling. It keeps track of the
available images, and makes it possible to delete existing images or
register new ones. The image store holds references to the underlying
layers for each image.

The image/v1 package provides compatibility functions for interoperating
with older (non-content-addressable) image structures.
