[cssom][css-variables] cssom defines property access using case insensitive lookups

As was decided at the last F2F, cascading variable properties are
referenced via a case-sensitive ident. However, the definition of
object model methods referred to in the CSS Variables spec such as
setProperty, lookup property values with a case *insensitive* lookup. 
That needs to be tweaked for the variables case.

In other words, the two lines below return different values:

  a = styleObj.getPropertyValue("var-foo");
  b = styleObj.getPropertyValue("var-FOO");

I think the object model spec just needs to include steps for special
handling properties that begin with "var-".

John
