- Add field ``remote_site_search_rss_url`` so you can set an explicit
rss url that we use for querying the remote site, instead of
appending a hardcoded ``search_rss`` to the site url. This means we
support non-Plone sites now.

- Set the User-Agent string to 'Mozilla/4.0' when querying remote
servers. Otherwise, some bad servers return a 403 Forbidden error.

- Add timeout value for remote RSS portlet searches. Default is 5 seconds.

- Load the zcml of some packages so Plone starts up correctly.
