cmf pack manifest.xml should generate a hashcode

[jrk94]

Hi all,

I would be great if the manifest.xml was not only version locked, but in the cmf pack it generated a hashcode. If the product did not support "force" where you install the same version twice it wouldn't be needed. but because it does. It should be supported

What would we want to hash here? In most packages, the manifest itself doesn't change, so should we hash the entire contents of the package? Seems a bit slow, wouldn't something like including the Git HEAD + dirty working copy state be a valid fast alternative?
