Update for Spine 4.0+

[davord45]

Spine version 4.0 and above have changed the curves in the JSON file. Before it was 4 variables (curves,c2,c3,c4), now there is a array called curve with 8 floats:

curve": [ 0.889, -169.87, 1.114, -108.54, 0.924, -264.13, 1.114, -373.86 ]

Spine now has x and y for translate,rotation and scale.
Can you please update the runtime so that it works with newer versions?

The 4.x version of Spine has not been released yet, and the version of the spine-runtime-cpp they provided is 4.0-beta which was updated 3 monthes ago with 3.8 version code merged. I prefer to wait for the official release version of spine-runtime. You could try to override the spine-cpp folder with the newer version of spine-runtime-cpp and build the engine.

I've update it to spine version 4.0.
