Save/Load and Main Menu Submenus

Redid all of the property panel UI prefabs (oof)
Implemented saving and loading of the game state
Moved sector generation to sector constructor (along with loading from save file)
Entity settings now separate from player settings
Player settings (incl. saved run) now statically accessible from game manager
Added animations and submenus to the main menu
Unified main menu settings and properties panel styles for prefab reusability
