Upgrade chances now visible in the upgrade window

No more guessing when upgrading:

• The upgrade window shows the real success chance of the next attempt (green, yellow, red) – Serendipity potion and a running upgrade event are included.
• It also tells you what happens on a failure: item lost or – with a Survival tincture – the level stays.
• Hover over a chest (in your inventory and in the item shop) to see all possible contents in percent.

The launcher fetches the update automatically. All numbers are on the website too: Chests & chances.
