Use percentage-based width for the sidebar

Browse Source 
Use percentage-based widths internally. This slightly impairs (user)
feedback but brings the sidebar configuration menu closer to the actual
configuration format (the user now configures percentage-based widths,
not absolute width values). As a bonus, the sidebar is now resized
automatically on each window resize (based on the percentage values).
