ilcorsaroblu: Update regex for better title parsing... (#3532)

Italian release suck, you can find S01E01 or 01x01 or even S01 E01.
So removed S and E from search (this bring in extra results) then try to parse and reconstruct the results
Hope for now is enough to have a better search, at least on Italian tracker, for the external tracker (where are present Italian release too), only god can tell ... Sonarr will parse the result during a rss sync, but during a search I think no result will present ... There are 2 possible solution
1. Find and eliminate all release that don't respect the standard
2. Make Jackett / Sonarr / Radarr a little smartest and include a kind of regional substitution during a searching phase
