Scouting App: Add keyboard shortcuts for note scouting

With keyboard shortcuts, note scouts don't have to stop watching the match
to switch between textboxes, they can just do Ctrl + 1/2/3 to switch
to the corresponding textbox.
Hovering over the textbox, will display a tooltip with the
shortcut to switch to that textbox.
