Add "Purge Minit Cache" button to the admin bar

[sidati]

Hi @kasparsd,

Why not add a Purge Button in the admin bar ??

    add_action('admin_bar_menu', function(){

        global $wp_admin_bar;

        $wp_admin_bar->add_node(array(
            'id' => 'minit_purge_button',
            'title' => __('Purge Minit', 'minit'),
            'parent' => false,
            'href' => add_query_arg(array(
                    'purge_minit' => true,
                    '_wpnonce' => wp_create_nonce('purge_minit')
                ), admin_url()),
            'group' => false,
            'meta' => array()
        ));

    }, 999);

@sidati That is an excellent idea. Thank you posting the code sample.

@kasparsd Glad you like it, By the way, if you have minutes, take a look to my pull request concerning the @import css functions https://github.com/sidati/minit/commit/3f0f618746f3a172b53582f24405977e8517a229

I like this! I dont think we should register it with an anonymous function though. It makes it hard to remove it for those who does not want it.

@kasparsd @ahansson89 why not adding some settings array with a filter like in JS plugins, so devs can enable or disable any core feature; something like :

    $settings = apply_filters('minit_settings', array(
        'admin_bar_button' => true,
        'move_css_import_to_top' => true,
        'comments_in_combined_file' => true,
        'minify_css' => false
        'exlude_externals' => false
    ));

I like this idea a lot!

That said, I think stuff like this could go in a different plugin like this: https://github.com/markoheijnen/Minit-Pro

You only need to chage wp_cache_flush(); and rephrase messages.
