Refine naming of commands in CLI

[JeffLowe]

Refine the names of the cli commands. Some were called out in meetings on week of 8.15

• we should call remove unlink at the code level w3up-client#3

Also, update some labels, like:

• add user-friendly labels for the “agent” DID versus the “account” DID

@jchris do you have specific examples of items we need to update?

[jchris]

This is a placeholder for applying feedback from users. I expect there will also be a global refinement (across services) as we work through how to modularize CLI and SDK components.

Currently the only thing I have is -- we should discuss renaming w3up upload to w3up add or w3up put.

This is probably more an SDK API question than a CLI question. Terms suggest their own logic: add / remove go well together, so do put / get / delete

@jchris in the short term I will add aliases. For instance, we use this now. eg. remove and unlink do the same thing.

I'm going to alias add, upload, up and link and put for this action. : #57

I think that's good for alpha, we can retag this beta so we don't forget to revisit before beta release.
