EditTagDialog: Make reset feedback work by calling

`set_reset_button()` in `UpdateModifiedField()` and catering for
  non-text in `IsValueModified()` (-1 original being same as 0);
  use new `ExtendedEditor::set_font()`;
  connect reset for "rating".
  Make "comment" `tabChangesFocus` to keep tab chain.
ExtendedEditor: New `set_font()` to get emboldened font to work and
  make reset feedback work for `CheckBox` and `RatingBox` by
  overriding `Resize()`.
RatingWidget: Allow tabbed focus and implement keyboard input.
