Improve input feedback styles and add focus style to checkboxes.

The correct/incorrect/partial-correct and focus box-shadows are also
made a bit more pronounced by removing the blur radius and making the
spread radius a tad bigger.  Basically, the same box-shadow used by
bootstrap for buttons and inputs.

To make this work well the margins between buttons and inputs needed to
be increased a bit so that the box-shadows of the two don't overlap.

The focus style has also been added to checkboxes.  I think this style
accidentally didn't get added for checkboxes when the
correct/incorrect/partially-correct styles were added for checkboxes.
This caused an undesirable lack of style when a checkbox was focused
that could be confusing (@Alex-Jordan observed this a while back).

The focus colors have been synchronized with those of MathQuill.
MathQuill will also need a change to its style so that MathQuill inputs
have the same box-shadow when focused.
