Complete package (package.usmc)

Complete package is simply a tar.xz file containing a MANIFEST.usm file and all the requisite files that would be acquired if the acquire script was run. That is to say, a USMC file could be created by simply running usm manifest acquire followed by tar -cJf ../package.usmc ..
