Update notes for v1.0.6

Truck City v1.0.6 has just been released. This changelog also includes changes made in v1.0.5 and v1.0.4:

• Balance: Curionian Spit: some items can’t be bought anymore; patch v1.0.3 increased the inital amout of money, which may enable the player to rush to research just buying everything and completely ignoring city building.
• Bugfix: regression bug introduced in v1.0.3 corrected, where research would not correctly start.
• Bugfix: corrected bug which caused science window to become impossible to close if inspecting the full dependency graph after clicking on a container icon, then used right click to close the full dependency graph.
• Bugfix: Leaderboard button in main menu is now disabled until the boards are loaded. Prevents a bug where only partially loaded leaderboards would be shown
