Feature: optional resources

[AntoninoBonanno]

Hi, at this moment if a file is not found a 404 error is triggered visible in the console.

Would it be possible to add the optional attribute to the resources, in order to catch the 404 error and not propagate it? (so as not to be visible in the console - for me it's not an error as I know that in that folder there may be no files)

For example, it is useful when initially there are no files in a specific directory but they can be added later to overwrite or customize the labels loaded by default.

Example:

export function HttpLoaderFactory(_httpBackend: HttpBackend) {
    return new MultiTranslateHttpLoader(_httpBackend, [
        {prefix: './assets/i18n/core/'},
        {prefix: './assets/i18n/custom/', optional: true}, // catches the 404 error and doesn't propagate it
    ]);
}

Thank you
