[mods] Changes to constants are not visible to user scripts

SystemParadox

I've been using screepsmod-speedup for a while. It just changes a bunch of constants to make things faster, cheaper, etc. Since the latest update the mod still works, but the updated constants are not visible to user scripts, which is problematic.

I suspect this is due to IVM. Is this something that needs fixing in the server or do mods need to be updated in some way?

Thanks.

It seems that to update the constants for user scripts in the isolated VM, mods need to do this:

if (config.engine) {
    config.engine.on('playerSandbox', (sandbox) => {
        sandbox.set('CREEP_SPAWN_TIME', 1);
    });
}

Note that mods still need to update config.common.constants as before, since that's what the main server engine uses:

if (config.common) {
    config.common.constants.CREEP_SPAWN_TIME = 1;
}

I have published screepsmod-fastbuild which implements these changes.
