remove the private key first if we already have a cert loaded prior to adding

Remove private key from ssh-agent before re-adding

Works around a bug, at least in openssh on os x 10.9.2, where re-adding a private key that has a new cert puts the agent into a weird state where there are many certs loaded for a single key. In that case none of the certs work.
0.3.1 release
Allow http/https urls in public key path

This is made more useful by things like this:

https://github.com/phobologic.keys

So people wouldn't have to email/IM their keys, they could be grabbed
semi-automatically.
