v1.0.11 - Hotfix #2

Some more bugs squashed:

• Extended waiting time for Steam auth, so less likely to be signed out when booting the game
• Fixed multiplayer difficulty hover text being empty
• Fixed sound slider still appearing after closing pause menu
• Pressing escape on the main menu does not exit to the account menu
• The language selection menu on first time boot, now auto-skips to the tutorial level after 20 sec
• Fixed that if you exit the "challenges" menu from "extras", you get thrown into the "singleplayer" menu
