Rename: coin PSC, exchange Poinbase, entry upgrade Web3 Governance Community

The entry network upgrade is the gateway to the whole mod, not only
mining: it now delivers the trading terminal and an RZX 50; rigs are
bought from Dr. Jackson, who always stocks one while the player has none.
The upgrade id changes (unreleased, no migration).
