Fix Twitter API

[Paul Vincent]

Twitter search is failling. This could bet due to 2 reasons:

1. Ian said Twitter has dropped support for non-https queries, we use http.
2. We don't rate limit the Twitter queries, although by virtue of the 2-query a minute, we should be under the 250 query / hour limit.

The error is:

Caused by: java.io.IOException: Server returned HTTP response code: 403 for URL:
