Calling interface functions

[TheOnlySilverClaw]

For scripting purposes, it would be very useful if Umka would allow interface methods to be called on a given pointer through the C API, either via umkaCall or a different function.

Will work on it!

For now, in order not to block your further work, I suggest you testing the plugin system prototype I made. It should give you all you need, with only a little more code on the host app side.

As #511 is now fixed, you can get rid of the zigDispose workaround and use umkaDecRef normally:

// Killing entities (since the host holds references to them)
for (int i = 0; i < numEntities && exitCode == 0; i++)
    umkaDecRef(umka, entities[i]);
