Graphic assets have been modified so hat they are of the size at which
they are displayed. This makes them safer for browsers not supporting
background-size property.

Settings text on the main ULS view can grow longer for some languages running out of space.
This change does the following to avoid that:
* Removes setting section explanations and shows them as a tooltip on hover.
* Adjusts style for adjusting space between setting sections.
* Keyboard image has been adjusted to match the display settings image.
