"What's New?" + M+ fix

New

• "What's new?" window. Auto-opens once after every update, the moment you open the main window (minimap icon / /nbk). Lists every change since your last login.
• /nbk news to reopen it any time.

Fixed

• Mythic+ "Remember player?" popup opened at the start of a run (when the keystone was inserted) instead of at the end. The popup now waits for a real run (at least 30 seconds of elapsed time) before showing up.
