UI Polish

[Ji-Rath]

UI should be kept minimal. We have some UI elements that can probably be simplified/removed.

• Remove 'Tab' UI. Merge quest UI with 'Esc' menu. This can be used if the player is lost. (hopefully shouldnt happen)
• Remove visible 'inventory ui'. Game scope should not require a full inventory UI.
• Implement new font to better match setting of the game
• Update background UI elements so better match the setting
