Some big changes.

Hey guys! I had days off from school so I got a lot of stuff done. 

• We're going to have a major GUI changes. Text box, day indicator, game menu, etc.
• Quick menu is now a part of text box now, and I added one (probably will be useful in the future) button-the hide UI button.
• Finally, the character menu code is finished! So I'll add the Character menu screen! And notification for character screen changes.
• Game menu (and its sub category like save game, load game, etc) are changed.
• Overall game progress.
