EIT fixup for UK DVB-T/S to extract sign language information

[Nick Morrott <knowledgejunkie <at> gmail <dot> com>]

The attached patches should correctly set the subtitle status of programmes having in-vision deaf signing broadcast over DVB-T/S in the UK, based on the EIT data.

My previous deaf signing patches are on tickets #4122 and #4125.

I have gone to the effort of including a patch for 0.21-fixes in the hope it can be applied (it is very trivial and has a definite benefit).

I will raise a related ticket that will add sign language specific rule clauses for the Custom Record and Power Priority screens which should round things out.

Nick,

See #2201, i'd like to implement the sign language modifier as a priority modifier. HD is already done this way, and that mechanism can be extended to support Signed showings.

I'm doing this slightly differently to the patch by fixing the currently handling of these items (m_ukCC regexp)

This will additionally pick out all the different types signalled AD - Audio Described S - Subtitles SL - Sign Language W - Widescreen

Thanks to Nick for doing a patch. I didn't use it in the end, rather I fixed the existing m_ukCC regexp to properly pull out the items of interet and apply them to the program data.

Been meaning to get this done for ages, and this ticket spurred me on to sort it out.

Thanks to both Nick and Stuart for this. I look forward to knowing when to expect what services - if the tags are correctly entered at source!
