moved opentv patterns from code-level to the provider configuration file

Browse source 
This permits to add/change patterns without touching the code.

In the original code of tvheadend there was an old pattern: it was
copied in ausat/skyuk conf file in order to maintain backward compatibility.
Note: now all the patterns are uniformly applied in a case-sensitive way (necessary for sky-it subtitle patterns)
