Change to machine config.

As outlined in the first post of #3. I haven't updated the vignette yet, but the readme is up to date. Check it for an example.

The rpc() interface is now has to have a machine argument in it every time, but dealing with multiple machines is much simpler. It might be worth exporting some kind of set_default_machine(my_machine)-like function that sets .pbd_env$RPC.LI$machine or some such. Then rpc() (et al) can be modified so that the machine argument is at the end of the arguments list, and if left blank it would use the .pbd_env default. This would be nice if you had to deal with one machine a lot I suppose. Another option would be to add an R6 class (or even just fake it with a quick custom job of lists), giving a syntax like:

m <- Machine("my-host", "username", ...)
m$rpc("mycommand")

I get the feeling you don't like those interfaces, but I think they're cute. And if we use Machine() for the "class" constructor and machine() for the regular interface, we could have both at the same time.

See slack.

You may want to do if(missing(machine)) so you can have a default when no machine is provided.

I blindly merged and pushed, and I did not test rpc0() and your rpc() ... Please check carefully.
