Search Engine Plugin

Some time ago, while implementing one of the new features I had to turn off the advertising of search engines. They existed, but were not really easy to add to the browser if you didn't know the exact URL. Today, I updated the service so that the plugin is easier to add.

The combination of languages for the advertised search engine is inferred from the URL and your settings. So the search engine advertised at http://pl.en.open-tran.eu adds an engine for suggestions between Polish and English, but the one at http://de.fr.open-tran.eu adds an engine for suggestions between German and French.
