Fix drawing of icons with alpha transparency

Browse Source 
Icons with real alpha transparency weren't being drawn correctly
because the NaTrayIcon was being set redirected in addition to the
window holding it. And nothing drew the icon onto the window holding
it. Use the newly added na_tray_icon_set_composited() to fix.
