Attempt to leverage IE9+'s native support for textual "select" events

[JamesMGreene]

IE9 and IE10 actually have native support for text selection events as a "select" event, not to be confused with the "select" events associated with textual form fields). It would be nice to leverage this native event rather than jerry-rigging together, although that also implies that a first-run test must be added/simulated to determine if such an event is supported.

Be forewarned that this native event may prove to be unsatisfactory as my initial testing with IE9 and PPK's "select" event test page suggests that the event only fires at the document and window levels rather than on more deeply nested elements. This is in disagreement with PPK's "select" event compatibility table, so additional testing will be needed to determine the actual status.

Alternatively, given that IE9+ supports this natively, this could theoretically be built into jQuery core as an event fixHook. However, I don't believe this approach will actually be possible as I think the fixHooks are only applied to existing native events in order to standardize/normalize their behaviors; browsers other than IE9+ do not offer such an event to fix. Discuss this possibility further with @dmethvin.

It appears that this will not be a feasible option unless we will NEVER want the event to fire deeper than at the "body" element.

Testing with IE9 on Windows 7 Professional (64-bit), such an event will only fire if it was hooked up (via addEventListener) to the body, document, or window. If you have a "select" event handler on a "p" tag within the body, for example, it will not fire!

In other words, the deepest element that this event will ever fire on [and will thus be the context of "this" in the native event handler] is the body. You will never have any node context deeper than the body (again, unless you're working with the old form-based selection events.

Reinvestigate this... all docs suggest this should work. Perhaps I didn't register as IE9 Standards Mode:
