New Menu & NPC routines system!

We updated the aesthetic of the main menu!

We also finally have our NPC routine system working:

• Now we have the ability to create routines for the NPCs, and they will follow them across different scenes of the game.

• At the same time, the action that each NPC is doing has a correlation with the dialogue system, and thus they will say different things to you according to their current activity.

• In this release we included the first 2 NPCs only, with VERY basic behavior. They don't even have animations yet!.

Pending: allow different routines for different days of the week.
