Leverage requirejs-plugins/has to conditionally load the Intl shim. fix #20.

[clmath]

This will allow to force the use of the shim using requirejs config like this:

require.config({
    config: {
        "requirejs-dplugins/has": {
            "Intl-api": false
        }
    }
}

This fix issue #20.

Can't you already force use of the shim via?

requirejs.config({
    map: {
        '*': {
            'ecma402/Intl': 'ecma402/IntlShim'
        }
    }
});

PS: It's still good for Intl.js to use has.add().

[clmath]

Yes you can (although, if I understand the documentation here correctly, it would be the other way around).

A better reason to use the has plugin is to leverage its build part.

[wkeese]

OK. Then, it seems fine to me.

[cjolif]

Looks good to me as well. @JCEmmons any objection to @clmath going ahead and merging this?

[JCEmmons]

I'm fine with it. Go ahead and merge...
