[Task] Batch Mode needs to go through menu screen

[Spydrouge]

• Currently: I am deliberately not addressing this task further than the Workaround until we/I know exactly how we plan for Buildbot to run our unit tests.
• Problem: Because the game launches in the main menu, running in batch mode will hang the game at the main menu before the game/unit tests launch.
• Workaround: Build game with only in-game scene (no menu)
• Long-term solution: Sense for Batch Mode when at the main menu and execute functionality to start a new game if Batch Mode is detected.
