v0.1.0

Project is usable now, but it's far from done and it's got some quirks, use at your own risk.

Things to be wary of:

1. Error handling is not very nice, so expect some raw rust errors instead of user friendly messages
2. profile add is currently not secured against overriding an existing profile, it will also re-generate associated ssh keys. In the future release it'll warn in such case and quit, and --force flag will be added
3. profile remove will show an error when any of the following is missing: profile file, private key file, public key file. However, it will still remove the rest.
4. clone command currently always clones to current working directory, option to specify a path will be added in future releases

This version doesn't work properly for pushing authorization
