Create "status" command

[mikedotexe]

The command will be:

csli status

and take no args or flags at this time.

It will return whether it can connect to websockets and whether it can connect to the local wasmd.

It's possible people don't have wasmd. The way to check if a person has wasmd is to install this dependency:

https://www.npmjs.com/package/shelljs#user-content-examples

and actually that first example checks to see if git is installed, so we'll use that.

Shelljs is a cool thing can that basically run a command on your terminal, but in your js code.

So we can pretend like we're typing wasmd start using shelljs, and that's what we're going to do in another ticket. For now let's get that dep installed and have something sane be returned as outlined.
