Made improvements for searching for anime on newznab providers, who have...

...n't straitened out there anime episode parsing.

Should provide more search result using for example: usenet-crawler, nZEDb, spotweb.

Newznab now also searches by q= querystring. Ommits the Ep.

Needed to cast ep (int) to str, for str concatenation

add searchstrings for searching newznab providers excluding the ep= paramater. I've added the episode to the q= param. querystring could look like: ?q=showname%2043
