First Post-Jam release

Added a few things to the game.

• NEW Global Events can occur during gameplay - these affect how much regular events affect your resources. This includes your alliance strength as well. You can have up to 3 global events active at one (Look out for one that changes the way the world looks!)
• NEW Scaling difficulty - I had a lot of comments saying it was too easy to keep the alliance filled so now the resources are affected more the longer into the game you are. This along with having global events active can lead to big losses in your alliance strength if you're not careful!
• You can now pause and quit during gameplay (Esc)
• Added a settings menu where you can change sound volume, screen resolution. and whether Global Events can occur during gameplay (This can be toggled during gameplay as well)
