Support general sibling combinator

[GoogleCodeExporter]

The general sibling combinator is made of the "tilde" (U+007E, ~) character
that separates two sequences of simple selectors. The elements represented
by the two sequences share the same parent in the document tree and the
element represented by the first sequence precedes (not necessarily
immediately) the element represented by the second one.

Example:

  h1 ~ pre

represents a pre element following an h1. It is a correct and valid, but
partial, description of:

<h1>Definition of the function a</h1>
<p>Function a(x) has to be applied to all figures in the table.</p>
<pre>function a(x) = 12x/13.5</pre>

I *think* these are correct for our test document:

[Test]
public void General_Sibling_Combinator()
{
    Assert.AreEqual(1, SelectList("div ~ form").Count);
    Assert.AreEqual(2, SelectList("a ~ span").Count);
}
