Today's lesson in not using Apple's private methods: somewhere between old/886f95f00431 and #9620 Apple changed their document icon setup process. Use the new methods and fix #9620.

* @class AIClickThroughThemeDocumentButton
* @brief This NSThemeDocumentButton subclass makes the window move when it is dragged.
*
* Normally, an NSThemeDocumentButton eats mouseDown: and mouseDragged: events for its own nefarious
* purposes, namely drag & drop of the window's document to other locations. We want to utilize the display
* of a document button, but we don't have an associated document, so dragging appears to just do nothing.
*
* With this replacement class, dragging the document button properly moves the window. The code is, for
* reference, a stripped down version of the code powering AIBorderlessWindow's dragging movements.
*
* On mouse down, the window's frame is noted; deltas as the mouse moves are used to determine the window's
* own movements.
