Fix for Bludit v3.x

[tiloschroeder]

With Bludit 3.x, the plugin only minifies a few last lines of HTML code.

To be able to minify all HTML code, we need to start the output buffering via the beforeAll hook.

The following code for the plugin.php works fine for me:

<?php

class pluginMinifyHTML extends Plugin {

    public function init()
    {
        // Fields and default values for the database of this plugin
    }

    public function beforeAll()
    {
        ob_start();
    }

    public function afterAll()
    {
        require_once('class-minify-html.php');
        $buffer = ob_get_clean();

        echo Minify_HTML::minify($buffer);

    }

}
