v3.0 - Major Dating Logic + Result Screen

In comparison so all the updates, this update (v3.0)  is one bringing out more stuff:

• In general terms,  everything has been very decoupled: there is a global script that calls different services depending on the needs. The cool thing is that there are no dependencies between the services.  Pretty cool pattern for Godot!
• The Dating Logic is there, but I still need to paste most of the content written by Everly. For the moment, at least we have the winning condition set: you have to have completed 6 chats with the other character. For the first version we will probably make it work like this, but we could complicate this far far more! 
• The Result Screen Factory is one of those services I described before. In this version you can try to call your mom, cook some paella or talk in front of the mirror to see the result screen in action. This needs still to be implemented in exercising and working .
• Settings, Game Over, Continue Screen: all of them have received a cool rebrush
• You cannot repeat an action on the same day! 
• And far far more! For the moment there is a debug button so that you can pass the day till the evening and  chat with the other characters!

Hopefully I can fix the problems with the YSorting and Z-index in the tiles before the deadline on the 31st!
