makes tumblr search seperate method, fixes tumblr search bug

Found tumblr search bug when searching for a term with whitespace in it. Twitter allows searches with white space while tumblr doesn't because of how they search for blogs (that is, the unique identifier that they search is the part before ".tumblr.com" so if there is white space it freaks out. Used a simple delete method no the search term but also moved the tumblr search out to a separate method.
