 Improve the performance of Live TV embedded in the Program Guide.

 Most of the Program Guide's DB and backend queries are moved out of
 the UI loop into a background helper thread, to minimize the chance
 of the embedded Live TV window stuttering.

 More work can and should be done to pre-cache scheduler data and
 channel tuning status, and to have the backend invalidate/update it
 when there are changes.

 The background computation introduces some guide navigation UI
 oddities, where the expensive-to-compute elements (the list of
 channels) update on the screen slower than other elements.

 There is still some slight stuttering on a single-core ION frontend,
 but most frontends should see a vast or complete reduction in Guide
 navigation stuttering.
