Summary Unsupported commands should have queryCommandValue() = "", not false

Test-case: data:text/html,<!doctype html> <script> var val = document.queryCommandValue("quasit"); alert(typeof val + ' "' + val + '"'); </script> Chrome 20 dev alerts 'boolean "false"'. This means queryCommandValue() is returning a boolean, when it's specced to always return a string. Gecko now returns the empty string, per spec <https://bugzilla.mozilla.org/show_bug.cgi?id=742240#c18>. IE throws, which we decided in bug 83993 was not acceptable. WebKit should return the empty string here. This probably doesn't have big compat impact, because false == "" in JavaScript.
