Don't use illegal json in configs

[Anarchid]

The feature that allows Circuit to have comments in its JSON configs seems to be fragile: ZeroK-RTS/Zero-K-Infrastructure#2596

Converting configs to a format that supports comments directly - e.g. hjson, - rather than in violation of its standard, should address that.

Also Zero-K-Infrastructure#2596 issue is not relevant: someone forgot to put comma in array declaration, as json parser informed inside infolog.

Added AngelScript. An option is to replace json config by AS script, supports comments.

Another reason to migrate from json is duplicate key entries - no error raised.
