Return entire hash when indexing document

[primeosu]

Not sure if this would affect other methods, but it would be nice to get the entire hash returned when indexing a document instead of just the "_id". Reason being is that I need to see the "_version" and "matches" when doing percolation.

For example:

p client.index( {'name' => 'test', 'foo' => 'bar'}, :id => 1, :percolate => '*' )

Returns "1" when I'd prefer it to return {"ok"=>true, "_index"=>"test_index", "_type"=>"test", "_id"=>"1", "_version"=>1, "matches"=>["test_query"]}. This is especially important when doing percolation at index time.

It makes sense to return the hash now, but in earlier versions of elasticsearch there was no useful information besides the id.

I don't think rubberband itself relies on the return value, but it would be a breaking change.
