This features addresses the game progression goal #'Complete castles functionalities'

Describe the solution you'd like

Here's what I've in my mind about the churches content right now:

• You'd be able to 'rest' here, the same way it works in churches
• You'd be able to check the castle blacksmith, forge, stable and grocery store (#79 )
• Perhaps some kind of job board, where you can get common missions
• And more to find out
