Rewrite the CLI

[ryugi]

Use https://github.com/clojure/tools.cli and the docstring extraction functions in https://github.com/clojusc/trifl.

Tasks (each of these should get their own ticket):

• provide detailed examples of ideal usage from the cli
  • for use by developers
  • for use by scripts/automation tools - will update in the future, as needed
  • for use by build matrices that need scripts to respect ENV variables - will update in the future, as needed
• find a good taxonomy for the anticipated full command set
• re-org the cli namespaces accordingly
• create new functions for tasks
  • config
  • config show
  • config help
  • db
  • db help
  • db init
  • db dump
  • projects list
  • project
  • project help
  • project create
  • tasks list
  • tasks list
  • task
  • task help
  • task create
• move help into new functions' docstrings
• update main/entrypoint function to work with clojure.tools.cli
• add dispatcher(s) for subcommands
• provide a bash auto-complete script
• update and/or remove the project.clj file aliases
• create a cli server that runs in the background and listens for commands
  • rewrite using UDP sockets (inet-address and sockets libs)
  • remove TCP server and dependencies
• create a lifecycle component for the cli server so it's brought up with the other components when the system starts
• create a cli client that starts up fast (cljs wrapping node, probably), has access to the file system, and can open tcp connections
  • rewrite the client to communicate with the new UDP server

Draft command list for commands that will run timi code:

timi help  ; also `timi -h` and `timi --help`
timi config [show]
timi db init <filename>
timi project create <name>
timi task create <project name> <task name>

Each of the above commands should also support -h or --help at the end

Commands that will be lein aliases:

timi deps tree ; alias for `lein deps :tree`
timi deps check ; alias for `lein with-profile +test ancient check all`
timi lint ; alias for `lein with-profile +test kibit`

Namespaces for the commands:

timi.cli.config
timi.cli.db
timi.cli.project
timi.cli.task

Also, a supporting ns:

timi.cli.parser
