Quests, Customization & Repairs

Added some new Castle/Village tabs which appear at random:

• Workshop - Allows to repair and customize your airship with custom parts and colored paint
• Quests - A quick way to earn money and get busy; for the moment you simply get a destination and a reward, but eventually will add different quest types such as kill quests or escort quests

Also added slight coloration of tiles to emulate cold or hot environments and other stuff that I forget
