Fontchooser improvements

I've made a few little improvements for ttkwidgets.font:

• Default font family and size option for both FontChooser and FontSelectFrame, and all subwidgets
• AutocompleteEntryListbox for FontChooser instead of a label and a listbox
• 3 lang translation for both FontChooser and FontSelectFrame (DE, HU, FR(just for consistency with other dialogs, I had to use DeepL for it))
• GUI redesign for FontChooser: LabelFrames, preview frame redesign, dialog buttons were moved
• FontChooser Toplevel improvements: master, .transient(), .wait_visibility(), .lift(), .grab_set() (just like in ColorPicker)
