DreamHostService:
* reverted connections/@active back to connections/@count (should have known better than to change something that used to work)
* fixed an NRE issue with showing the host status when no connection limit is provided
status.xslt: show pending connections as well
Removed services and status XSLT altogether since we actually prefer raw XML output.
