v0.3

- Added 2 new rooms, Barracks which shows recruits (split from the previous hall that had both recruited and available adventurers) and Training Hall (still WIP room where you can assign adventurers for training)
- Experimenting with adding 2d sprites representing the adventurers in the headquarters to bring more life to it.
- Added basic templates for adventurer gear and hair, very rough and needs to be redone at some point but it's better than naked adventurers
- Created UI theme and applied it to all main scenes, hoping that will make it easier to try out different styles with the UI 
- Some QOL improvements to better show adventurer status when in inspect mode

- Fixed following crash:
Crash when trying to craft bandages. The bandage recipe does not have a secondary slot which makes it null in release build but not when launching the game in the editor. Added null checks for secondary slots in places that use it and looked at other resources for potential similar issues.
