REPL related improvements and fixes (#3545)

Motivated by - https://github.com/open-goal/opengoal-vscode/pull/358

This addresses the following:
- Fixes #2939 spam edge-case
- Stop picking a different nREPL port based on the game mode by default,
this causes friction for tools in the average usecase (having a REPL
open for a single game, and wanting to connect to it). `goalc` spins up
fine even if the port is already bound to.
- For people that need/want this behaviour, adding per-game
configuration to the `repl-config.json` is on my todo list.
- Allows `goalc` to permit redefining symbols, including functions. This
is defaulted to off via the `repl-config.json` but it allows you to for
example, change the definition of a function without having to restart
and rebuild the entire game.

- Updates the welcome message to include a bunch of useful metadata
up-front. Cleaned up all the startup logs that appear when starting
goalc, many of whom's information is now included in the welcome
message.
