[horde] Excessive Weather API calls

I installed redis from EPEL repo, configured it (not much to that  
really), installed pear nrk/Predis, then setup  
$conf[hashtable][driver] Horde Distributed Hash Table to use localhost  
Redis Server, then set $conf[cache][driver] Horde Caching to use a  
Distributed Hash Table server, and $conf[cache][use_memorycache] to  
Hashtable.

Is that all how it should be for Hash Table / Redis usage?

Test.php probably needs updating for redis / hash table support...

Anyway, with all of that done, the Horde system does seem marginally  
quicker with it all cached, and my weather calls have dropped to  
manageable levels.

Thanks
Simon.
