[mythtv] New duplicate check method 'smart'

[Martin Long]

I've created a new 'smart' duplicate check method. I normally use either
subtitle, or description. Sometimes a series flips between using a subtitle,
and not (particularly with the UK eit guide data!). 'Subtitle and
description' is pretty useless for me, because a) if the subtitles are none
existent then programs don't match b) if subtitles are present they can be
fouled by small differences in the description - the whole reason for using
subtitle in the first place.

So, I created 'Subtitle then description (smart)'. This first checks the
subtitles match, however, if no subtitle exists, then and only then will it
check the description.

I've done a little testing, and it seems to work ok, and helps to iron out
some of the inconsistencies caused by the uk eit data. Anyway... see how it
goes. I've attached patches for trunk, but they apply to 20-fixes ok.

Mythweb patch also included, but you'll need to update your .lang file with
a string for 'Subtitle then Description (smart)'. I updated the english one,
but spooked the diff, so i left that out.
