Title: modified changelog and added rename-tag

I modified git-changelog to accept an output file as parameter:
`git changelog done.txt`
also I added `-l` as a shortcut switch for `--list`

then I created a git-rename-tag command, usage:
`git rename-tag old new`

I guess you'll have to bump the version number for this though. Is there a reason why you didn't with the last pull request??
