ReportResponse's parse_total_results doesn't parse totalResults

[proby]

After switching the response format from XML to JSON the totalResults value comes back in a hash like this:

"openSearch$openSearch:totalResults": {"$t": "4215"}

The current implementation will always return 0. I think the method should be changed to something like:
feed? ? parsed_data['feed']['openSearch$totalResults']['$t'].to_i : 0
