Modifies dev server to produce stateful gzip and modify image_to_live to use it.

Browse Source 
TEST=Tested with image_to_live, memento_updater without image_to_live

This mimics the update process of the real image for the stateful partition.
By moving this the update into a separate script, I can add it to the gmerge
package such that developers will not have to use image_to_live.  This change
also removes the dependency on tar.
