Extend the trial playtime limit to be longer

Currently, the Minecraft demo has a strict time limit of 5 in-game days, which is only about 1 hour and 40 minutes of real playtime. This is way too short to properly explore a world, try out redstone, or see if a computer runs the game smoothly. Please change the trial version to give players more hours of playtime so we can actually experience the game before deciding to buy it
