Change introduction text when doing jsipfs init

[victorb]

Today, when running jsipfs init, you get the following message:

initializing ipfs node at /Users/phil/.ipfs
generating 2048-bit RSA keypair...done
peer identity: QmeLtmb2QUkm5DAVZKANV7YydAFBP6ATiZATD1UzvhAwYE
to get started, enter:

     jsipfs files cat /ipfs/QmegvLXxpVKiZ4b57Xs1syfBVRd8CbucVHAp7KpLQdGieC/readme

But that command will not work because subfiles are not implemented yet (#478)

In the meantime, we should change the hash to point directly to the file (instead of hash/file it should just be hash), to prevent more confusion from this.

Is there a working command I can run to test it?

I've done this :)

@chovy npm i ipfs -g && jsipfs init && jsipfs daemon should get you rolling :)
