Use cargo workspaces (#37)

* Switch to Cargo workspaces

Breaking things into "client", "server" and "common" makes managing the
codebase much easier!

client - anything running on a user's machine for adding history
server - handles storing/syncing history and running a HTTP server
common - request/response API definitions, common utils, etc

* Update dockerfile
