White space to fill with other options.

When categories are filled, it would be useful to have a choice of white space for when the category is not on the given list. For example, the roles don´t have categories such us "productor" or "presentadora". The idioms don't have categories such us "spanish and galician", the theme of the program don't have categories such us "humor". And so on.

Right now it's only possible to choose a main category, this list corresponds to iTunes's categories and it will be bigger in the next version but it won't be possible write custom values on it due to compatibility reasons.

On the other hand, the roles list should be more flexible in future versions.
