Feature request: expose errors to plugins

By now errors in Webpack is handled like this, an error message:

        errors: function(errors) {
            status.text("App updated with errors. No reload!");
            okness.text("Errors while compiling.");
            $errors.text("\n" + stripAnsi(errors.join("\n\n\n")) + "\n\n");
            header.css({borderColor: "#ebcb8b"});
            $errors.show(); iframe.hide();
        },

If that code is exposed then we may get error messages like this with plugins, and it can be quite convenient, as it already was in ClojureScript projects.

update:

I made a prototype https://github.com/mvc-works/webpack-hud

I exposed some events to the window now with 06c7773e9b6a0e3dbe43e53f605dbc221edc4e29. An example of how to use it:

window.addEventListener('message', function onWebpackMessage (msg) {
    if (!msg.data || !msg.data.type) return;
    switch(msg.data.type) {
        case 'webpackOk':
            console.log('bundle compiled ok');
            break;
        case 'webpackErrors':
            console.log('There were some errors', msg.data.data);
            break;
    }
}, false);

Let me know if you have any feedback. It’s not released yet.

Closing this since the feature has been implemented. Let me know if you don’t like the API or want to make some changes.
