Client Cleanup

[jeichorn]

• [x] Fix All visible paths
• • [x] signup
• • [x] app create
• [x] account.json contains only org info, not the user info
• [x] warn on signup if accounts.json already exists

Paths are the docker version instead of the real one

Wrapper needs to pass in the real path, and all paths need to be displayed with a helper

For the accounts.json thing we're just merging in any new signups to the existing accounts file.

Not using a helper to display paths. We wound up mounting $PWD as a volume (#35).
