[Plugin: Audio Player] Small bug fix for AudioPlayer 2.0.4.1

There’s a minor bug on line 176 of audio-player.php

$pageName = add_options_page("Audio player options", "Audio Player", 8, $this->optionsPageName, array(&$this, "outputOptionsSubpanel"));

should be

$pageName = add_options_page("Audio player options", "Audio Player", 'manage_options', $this->optionsPageName, array(&$this, "outputOptionsSubpanel"));

The existing code generates the following notice: Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead.
