Use different api4.thetvdb.com endpoint for getting all the series

[roosnic1]

Hi

I had a problem with the series "Mit offenen Karten" in french "Les Dessous des Cartes". The function GetShowInfoByTvdbId in ItemLookupService uses the get_show.php?tvdid={tvdbid} but in the specific case of "Mit offenen Karten" get_show returned the episodes with the french episode titles. Because of this the MatchingStrategy.ItemTitleExact failed since it's comparing German to French episode titles.

With the endpoint https://api4.thetvdb.com/v4/series/$tvdbId/episodes/default/deu it's guaranteed that the episode titles are in German as long as their is a translation.

I tested the change with "Mit offenen Karten" and "ZDF Magazin Royale".

I also added a new rule for the rulesets but i read in an issues that @PCJones plans to make that more dynamic anyway. But to be complete here the added rule:

{
      "id": 98,
      "mediaId": 63,
      "topic": "Aktuelles und Gesellschaft - Hintergrund",
      "priority": 99,
      "filters": "[{\"attribute\":\"duration\",\"type\":\"GreaterThan\",\"value\":\"10\"}]",
      "titleRegexRules": "[{\"type\":\"regex\",\"field\":\"title\",\"pattern\":\"^Mit offenen Karten - (.+)$\"}]",
      "episodeRegex": "",
      "seasonRegex": "",
      "matchingStrategy": "ItemTitleExact",
      "media": {
        "media_id": 63,
        "media_name": "Mit offenen Karten",
        "media_type": "show",
        "media_tmdbId": null,
        "media_imdbId": "n/a",
        "media_tvdbId": 109331
      }
}

Hey, thanks for contributing! I've been super busy and missed this somehow, sorry about that!

I will definitely merge this if it holds up after some testing :)
Should fix #35 #50
