[Screen] Search movies based on free text

[isabelcosta]

The idea is to start integrating search for movies and then pass to tv shows and then multi search.

TODOs:

• hide keyboard when search button is clicked
• limit the search edit text to 1 line max and 20 characters
• enter key on keyboard must represent a search action
• [fix] after clicking a detail, when going back to the search screen, all search results disappear
