[Plugin: All in One SEO Pack] minor problems in latest release

Couple of minor problems in the latest release (1.4.6.15) of all-in-one-seo-pack:

1. all files are duplicated because of extra “trunk” directory in the subversion tag directory
2. call to load_plugin_textdomain doesn’t take into account the fact that the WordPress content directory may be different. Instead of:

   load_plugin_textdomain('all_in_one_seo_pack', 'wp-content/plugins/all-in-one-seo-pack');

   this should be:

   load_plugin_textdomain('all_in_one_seo_pack', null, 'all-in-one-seo-pack');

   That will automatically prepend the plugin directory, whatever it is.
