Fixes godot-escoria/escoria-issues#48
Fix: tween was stopped_all before starting


Fix: reload locale from settings in ESCGame

Since main menu and pause menu are now loaded from ESCGame and not from escoria.gd, this must be done here.

But save and load are broken at the moment...
Fix: check save and load after main menu changes
