Try to authenticate with all available keys

[goerz]

It appear that Blink will use key-based authentication only if this is requested explicitly with the -i options for SSH, respectively -I for mosh. This is different from how mosh/ssh work on my laptop, where it tries all available keys for authentication when ssh/mosh is invoked without options. Blink should either behave in the same way, or document the need to use -i/-I explicitly.

Also, it would seem feasible to add an option the the Key configuration for setting a "default" key, or "try all keys". In addition, or alternatively, a Hosts section in the config (to be implemented) could associate specific keys with specific hosts.
