ClassicStand V2.6

Major game improvements.

Added ingredient spoilage overnight. Ice melts significantly, lemons rot partially, and water evaporates slightly each night. Sugar, salt, and cups are unaffected. A message at the start of each day tells you what was lost.
Added a price setting prompt at the start of each new day. You can set your own price per cup, with a suggested price based on your current day and level. Charging more earns more cash per cup but makes customers less patient.
Added a daily weather announcement at the start of each new day. It includes the date, temperature, and a hint about what kind of crowd to expect based on the weather.
Added a customer tipping system. Happy customers now occasionally leave a tip on top of the cup price. Both the chance and amount of a tip scale with your reputation, so keeping customers satisfied pays off more over time.
Fixed a bug where returning from the daily summary on day 2 and beyond would immediately trigger the wave end announcement instead of starting a fresh wave of customers.
Added keyboard shortcuts to check customer status. Press A for arriving customers, W for waiting customers, and L for leaving customers.
Restored random events. Events were accidentally removed during the customer system rewrite. They now fire with a 60% chance at the end of each time period before the next wave begins.
