One more fix for optgroup and select all.

If you collapse all optgroups in the 'selectable' list, then call the select all method, the optgroup header labels still exist in the 'selectable' list but shouldn't be there.

Also I made the select all optgroup example work the same as the regular optgroup example, IE: Load the screen with all optgroups collapsed.
