All OpenSearch entries should be separate actions, not parameters to the "Search Internet" action

At the moment, the OpenSearch plugin works like this:

- Fire up Do
- Type and select "Search Internet"
- TAB
- Type my search query "macbook pro"
- TAB
- Type to select "Ebay"
- ENTER

A suggestion to have it work much more convenient was:
- Fire up Do
- Type and select "Ebay"
- TAB
- Type my search query "macbook pro"
- ENTER

So instead of showing the OpenSearch plugin as one function (Search Internet) every search engine should be integrated as a separate entry in the first menu.
