Use load_plugin_textdomain as recommended on docs:

 * http://codex.wordpress.org/Function_Reference/load_plugin_textdomain
Translate the string after applying html_entity_decode(stripslashes()) (#20)
Add trailing slash to comment-subscritions page.

 * Wordpress will redirect by default http://$BLOG/comment-subscriptions?foo
   to http://$BLOG/comment-subscriptions/?foo but this redirection will break
   the qtranslate URLs.

 * With this change we avoid an unneeded redirection, and we make qtranslate
   happy :)
Translate the string subscribe_reloaded_subscribe_without_commenting
