Subject: [PATCH] EPG: Cache FreeRecorderList query to remote Backend

When the EPG during LiveTV shows up cache the result from the first query
of GetFreeRecorderList to the backend in a local vector because it takes
time and is repeated for each row and update of the guidegrid which is not
acceptable e.g. for a windows remote frontend.
