Reorganize repository

[themightychris]

Remove the vue frontend from being the main content of the repository, and organize the top level like:

• lib/: gitsheets npm package (published library)
• cli/: gitsheets-cli npm package (published CLI commands bundle, provides git sheet * commands)
• server/: gitsheets-server npm package (published HTTP API server)
• web/: vue frontend UI

Future

• vault/: electron app that bundles vue frontend and server for use on local git repositories
