Adding additional actions to Google Suggestions.

This change adds new actions to google suggestions. It does not change the default search action, it only adds new ones, so the user can use google suggestions to quickly get candidates for a search (e.g. typing "albe" for Albert Einstein) and then send the selected candidate to various search sites (e.g. Wikipedia or Youtube).

All search urls are customizable and the new actions are grouped together so they can be easily added to other sources to if the need arises.
