Various misc improvements to camp crafting

-Hide errant message claiming camp NPCs can't craft liquid
-Update non-camp crafting message to say that liquid crafting IS available at camps
-Give the player a notice if there's nobody assigned to work at camp, instead of just silently not crafting
-Extract crafting mission's description for translation
-Pre-check and WARN if we don't have anywhere to store liquid before the crafting is assigned
