Rotten tomatoes rating is ordering alphabetically

[pdrbrnd]

When sorting by Rotten Tomatoes rating, we're getting the results ordered alphabetically: Bullet 70%, misconduct 7%, the wall 65% ^ In this case, misconduct should be the last in the list, but alphabetically (strings) "7%" is greater than "65%".

To solve this issue we need to:

• when getting information from OMDB, we need to parse it to save it to the BD as integer (and not text). it can be an additional field in the table
• we need to create a migration that does the same for any existing movie in the DB
• we need to manually add the '%' to the front-end, when rendering the rotten tomatoes badge

The same can be done for IMDB and Metacritic. create an additional field for the parsed ratings (0-100 integer).

This would make it much more future-proof
