Sorting
Fix for issure #48

Fix for add recommended movies.
Reworked add recommendations

Add Recommendations has been reworked to ask for data and display the
result.
Imdb.php makes the request to imdb and filter out movies that do not
meet the criteria.
engines.php propergates the call from add_recommended_movies.php to
imdb.php as a middle man.
