no one's gonna drag you up

Can build and spray paint (spray paint seemed appropriate, maybe markers too?) signs via the examining of the sign.

When examining a sign with writing, I put the display in a pop-up. Not sure if this is good or annoying, I'm a bit mixed on it. Only plan on doing this with the examine keyword, other interactions will be player only messages.

Fixed some herpy derpy mistakes (like furniture ids not equal furniture names).
