GUI: Fix the caret drawing over the scroll bar in the list widget

Also remove the unused linesWidth variable and fix the hlLeftPadding and
hlRightPadding widget attributes to actually work.

There are still issues remaining with the caret in the list widget due
to the ellipsis being used to shorten long text. Ellipsis is accounted
for when drawing the text but not when computing the caret position.
