[mythtv] Localizing Category in Program Guide

[Torsten Martinsen]

I noticed that the categories ('kids', 'news', etc.) shown in the
Program Guide are not localized. Looking at the source, there does not
appear to be any attempt at looking up a translation for the category
string retrieved from the database before displaying it. Is anybody
working on this? Otherwise, I will probably have a go at it myself.
