Bug in Actions

The wysisyg editor I was using was choking when it tried to find
the JavaScript variable, twitt_plugin_url.

If fixed that in my code base by commenting out:
add_action(‘admin_head’, ‘twitt_admin_ajax’);

And adding this in its place.
add_action(‘print_head_scripts’, ‘twitt_admin_ajax’);
