Versions/upgrades

[shermp]

I noticed your little note regarding a versioning mechanism. Is it too early to discuss this? 😀

One option is to do something similar to what I prototyped in NDB. Another potential option might be some sort of external version file(s).

Ideally, a mod should be able to be included in a KoboRoot.tgz without fear of clobbering a newer version that is already installed.
