Range.detach is now a no-op

[thomasbachem]

Chrome 36 shows the following warning in the console when using rangy:

'Range.detach' is now a no-op, as per DOM (http://dom.spec.whatwg.org/#dom-range-detach).

Triggered by:

if (isHostMethod(document, "createRange")) {
    testRange = document.createRange();
    if (areHostMethods(testRange, domRangeMethods) && areHostProperties(testRange, domRangeProperties)) {
        implementsDomRange = true;
    }
    testRange.detach(); // <-- TRIGGER
}

I removed that call in commit 601b80c. The latest alpha release on GitHub has the fix.
