Please add bitbucket support.

BitBucket should already be supported

sail run https://bitbucket.org/username/repo

[coadler]

You're also able to change the default host in the config

So sail run username/repo will expand to sail run ssh://bitbucket.org/username/repo instead of sail run ssh://github.com/username/repo

so, I could have just changed it to `sail run github/org/repo?

[coadler]

I forgot you needed a schema if you provide a host to sail run

It would be sail run ssh://github/org/repo

[teddy-codes]

I ended up changing it anyway because it is easier to go with the grain than against.
