Updated KAT search.
Previously this used the advanced-search format, which often doesn't provide any results for several weeks after a show has aired. This update adds a secondary search which is a bit fuzzier, using the search string format: "Season Name" S01E01 which brings back more results. Used delegates to keep it dry. Split out feed parsing into a separate function to aid Single Responsibility. Also re-enabled the verified:1 parameter. This is the first time I've looked at Python code so happy for feedback of any sort.
