Implementation of Subscenes, SceneGroups and Gamemodes

Standardizes Gamemodes to be an actual class with data and utility functions that can be parsed
Adds inspector field handling for selecting gamemodes
Updated Scene class to work with Gamemodes for the gamemode field
Updates editor suite elements to be able to create SubScenes, SceneGroups and Gamemodes
Adds ability to convert SimGroup to SubScene
Updates BaseUI's chooselevel menu to have gamemode selection and filters shown levels based on selected gamemode
