More buildables, some fixes, upgradable smartfridge

- Fuel is now available in the tier 4 reagent list for buildable chem
dispensers.
- Seed extractor, gibber, and recycler can be built, but having better
stock parts has no effect.
- Smartfridge can hold up to 1500 items by default instead of 999,
upgrading matter bin allows it to hold more.
