* fix double space to single space
* use consistent punctuation in messages

Fix for failover error in status_network_tag caching; when no tags present in table we would return an array with one empty element instead of no elements when getting the cached data.

Use Status_network's caching settings when loading Status_network_tag entries; cache entries are batched per site and will be cleared when tags are inserted/deleted using the main interface.
(with fixes from tagcache branch)
