    fontchooserwidget: Simplify function
    
    - Don't do unnecessary casts
    - Fix weird variable declaration indenting
    - Fix loop indentation
    - Use a for loop for iterating over a list, instead of a while loop
    - Casefold font name only once, instead of every iteration
    - Remove needless true_var = true_var && TRUE assignment
