This reduces the number of assets needing to be sent on join by 150ish.
- Nanoui scripts modified to load templates in parallel instead of one at a time.
- Nanoui scripts modified to be willing to load from the resource bundle if available, falling back to ajax-loading the individual templates if absent.
- Adds "paintable" flag to pipe recipes so we know if we can paint it.
- Ports the RPD from Yawn Wider.
- Brings RPD sprites from /tg instead.
- Slightly refactors recipes to keep type-specifc vars on subtypes.
- Refactors RPD UI icons to use iconsheet assets: Instead of sending each individual icon to the client as needed, we declare an icon sheet asset and send the entire thing to client. Then we just use the given CSS classes to display the icons!
- Adds icon sheet asset datum for pipe and diposals construction.
