* Add commands to print the default configuration
When updating a software I often want to compare my configuration with the
configuration of the new version. To make this possible atuin can now print
the default configuration.
This also updates the example files with the actual values used as default in
the settings.rs files.
* Changed command name to 'default-config'
* Fixed merge
* 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
