Bankruptcy (Game Over)

Adds a bankruptcy / game-over rule that the base game does not have. You get an early warning the moment your balance drops below zero, with a live countdown, and a final notification once bankruptcy triggers and the game is force-paused. Configurable in the mod's own settings: choose whether the timer is based on real simulated game time (default, immune to calendar speed tricks) or on the in-game calendar year, and pick a difficulty for each. There is currently no way to undo bankruptcy in a given savegame other than removing the mod.
