* Fix `fem` caller unnecessary arguments (Caused by regex most likely)
* Fixed xray displayable opaque Render flag (superseded by internal Ren'py changes)
* Fixed Doll animation concatenation to list
* Added checkpoints to forbid the editor from rolling back to menu context
* Added forced checkpoint for when the editor is being opened to avoid rolling back to before it was opened (by opening a console for example)
* Alleviated the issue for when the game tries to recover from the place it cannot stop rolling back, but version var is unavailable because of it being not initialized in that moment
