[mythtv] Updates for Master_iconmap - Chicago

[Matt]

Xris and daniel -

   I submitted a patch to the master_iconmap a few weeks ago for
channels in Chicago as well as some missing national broadcast cable
networks.

I've noticed that several have been committed, but mine must have been
missed.  Just wanted to see if you could commit my updates with the
rest.

Thanks!
Matt
