hardfork: fix more major/minor issues
Also add some more tests, and rename some instances of "version" and "add" for clarity. NOTE: the starting height values are sometimes wrong. I suspect this is due to the hard fork reorg code being buggy, since they're good when syncing after the fact. However, they're not actually used by the consensus code, so I'm ignoring this for now, but this needs debugging.
