Homunculoid Customisation

Finally got round to explicitly pointing out that homunc option slots, while intended to support long-term character choices, aren't permanently fixed — you can visit your character's dodgy garage of choice, hop in a nutrient tank for the afternoon, and let an untrained grease monkey swap out your modular factory options.

Also, new factory option: a high-gain directional antenna pod bolted to your head, for look-to-lookup PineaLink ID snooping. Enjoy!
