+Convenience method `git_bitcoin_address` can be used for retrieving Bitcoin addresses.  If you give it a Bitcoin address it will return the same Bitcoin address; if you give it an Openname it will return the Openname user's Bitcoin address. Useful for allowing end users to either directly specify a Bitcoin address or provide a Openname in the same input field.
