Error handling example in wiki documentation swallows warnings

[vjpr]

From https://github.com/webpack/docs/wiki/node.js-api#error-handling

var webpack = require("webpack");
webpack({
    // configuration
}, function(err, stats) {
    if(err)
        return handleFatalError(err);
    var jsonStats = stats.toJson();
    if(jsonStats.errors.length > 0)
        // PREVENTS WARNINGS SHOWING
        return handleSoftErrors(jsonStats.errors);
    if(jsonStats.warnings.length > 0)
        handleWarnings(jsonStats.warnings);
    successfullyCompiled();
});

Warnings should be logged first, because some warning may be the cause of soft errors, for example "critical dependency warnings".

The return handleSoftErrors prevents warnings being shown.
