Create changelogs from non-downloaded repositories

[rafinskipg]

Git does not provide the functionality of retrieving the history from a repository you have not downloaded.
In order to have the feature of logging remote repositories without being in a repo folder some code has to be written.
I think in terms of functionality it should do something like this:

Whenever a user types -r REPO_URL on a folder that it's not a git repo:
Create a folder called .tmp (in the git-changelog directory?)
Go into that folder and clone the remote repo
Do the git log in that repo
Remove the folder .tmp after some time.
This will be time expensive.. but i think its a cool feature
