Description

Currently the system in place to go back to the main menu when the users JWT has not been refreshed has a few issues, notably:

1. [game_restart(https://manual.gamemaker.io/lts/en/GameMaker_Language/GML_Reference/General_Game_Control/game_restart.htm) does not reset global variables
2. Game assets such as objects within the asset browser that have been modified at runtime will not be reset (such as sprites origin or image index)
3. Dynamic resources will not be cleaned up.

Impact

We should implement a proper system to go back to the main menu:

1. Ensure that any instances that should be destroyed when leaving rm_world are destroyed (such as players, any singleton objects that will need to be re-created, etc)
2. Ensure that dynamic resources are cleaned up (include things such as EventAggregator.Unsubscribe, JsonRpcClientProtocol, etc.
3. Test thoroughly and check with debugger that instances and variables are reset correctly and everything still behaves correctly end-to-end.
