Unable to add custom formatters for MessageFormat

[nsamarak]

When using the i18n-node with MessageFormat, you're unable to add custom formatters to MessageFormat by using the static MessageFormat object. The example below illustrates adding a custom formatter to the static MessageFormat object.

MessageFormat.formatters.moment = function () {
    return function (value, locale, arg) {
        return moment(value).format(arg);
    };
};

The issue is caused by i18n-node packaging its own version of MessageFormat, which results in i18n-node having a different static MessageFormat object than all the other NPM modules. This because all the other NPM modules that depend on MessageFormat are looking at the top-level MessageFormat installation.

The MessageFormat lib that i18n-node requires:
APP_ROOT/node_modules/i18n/node_modules/messageformat

The MessageFormat lib that all the other modules require:
APP_ROOT/node_modules/messageformat

I tested deleting APP_ROOT/node_modules/i18n/node_modules/messageformat
and that works great -- now you can add custom formatters to the static MessageFormat object.

Should i18n-node stop packaging its own version of MessageFormat?
