Godot 3 - API 1.2

[Endojo]

This is not really an issue but I had no idea where to put this

I just wanted to let you know that I was glad to find your code for using the GameJolt API. I made some changes to the code to use the 1.2 API (seems like you are in the same progress which I didn't know when I started programming)

So this "issue" is just for posting the changes: https://pastebin.com/nFxbhf33 - I commented what I changed, so if you're interested you may check it out :)

(without comments it's <180 lines but the new API features like friends are still missing)

Maybe you don't like some changes but I figured that there is no harm in posting them ;)

Thank you for making this!
