MesoColumn Theme & BuddyDrive : fixing user nav css issue

functions.php

<?php
/**
 * Override BuddyDrive default css by filtering buddydrive_global_css
 * 
 * The array to return needs to be like :
 * 
 * array(
 * 	'stylesheet_uri' => url to the new css file
 * 	'deps'           => array of registered css dependencies
 * )
 * 
 * BuddyDrive uses dashicons, so by default $css_data['deps'] = array( 'dashicons' );
 * In this filter i don't edit it. But if theme author is using a custom icon font and registers
 * it using wp_register_style(), then it can also override it from this filter.
 * 
 * For this example to work, you need to :
 * 1- copy this code and paste it at the end of theme's functions.php file
 * 2- create a new subdirectory to /wp-content/plugins/themes/mesocolumn/lib called buddydrive
 * 3- then copy paste the /wp-content/plugins/buddydrive/includes/css/buddydrive.css file into the folder created at 2
 * 4- you should have : /wp-content/plugins/themes/mesocolumn/lib/buddydrive/buddydrive.css
 * 5- Remove line 234 of this file to have :
 * nav#buddydrive-item-nav ul {
 *	list-style: none;
 *	margin:0;
 * }
 * The problem came from the overflow:hidden css rule.
 * 
 * 
 * @param  array  $css_data the stylesheet and eventual dependencies
 * @return array  $css_data
