 * =============================================================================
 * Adiciona partículas nas cenas menu
 * É possivel ativar uma partícula diferente para cada cena ou desativar a 
 * partícula em cenas especificas.
 * =============================================================================
 * As imagens das patículas deverão ficar na paste /img/menus/
 * =============================================================================
 * No caso da opção Unique Particles estiver ativada cada partícula deverá 
 * seguir essa nomeação.
 *
 * SCENE_NAME + _par.png
 *
 * Exemplo.
 *
 * Scene_Menu_par.png
 * Scene_Item_par.png
 * Scene_Skill_par.png
 * etc...
