Add IMDB and Wikipedia link to series

Wikipedia link just Googles 'serie name + Wikipedia' and goes to first result, it's not always accurate but it is in most cases.
IMDB link takes you to the IMDB page using the provided IMDB_ID, and the button isn't shown when a serie
doesn't have an IMDB ID which does sometimes happen.

For now the links row is just at the top of the serie details, above the genre, airdate and such.
