Toribash macOS x64 support

Hi Mac players,
(greetings to Windows and Linux players as well but this won't be any important for you)

64-bit version of Toribash is now out of beta and is available for all macOS users. For those of you who already upgraded to macOS Catalina, this means you can play Toribash again - and for everyone else that you will now be able to choose which version of the game you would like to install.

Currently we plan to continue support for both x86 and x64 versions, but you'd likely want to switch to 64bit version as we might drop x86 support later with future updates.

That's all for now, have fun playing! ːorganiccucumberː
