Default to deploy command, not status.

Now that we preview all commands before running them it makes sense to
default to deploy, since it does the same as status but you also get
the option to run a deploy.
Allow use of first initial to identify remote.

Only works if the first initial for all remotes is unique. For
instance, if you have staging and production remotes then you can just
type “deploku s”.
Bump to version 0.0.4
