console.lua: add a scrollbar
Add a scrollbar to give a visual representation of the size and position in the items. It is not clickable. The counter is moved above the scrollbar to free up a line for an another item, simplify calculations, and prevent the selected item from jumping from the second to the first line as you type. In terminal output there is no easy way to draw a scrollbar to the right due to Unicode widths. This just moves the counter into the prompt.
