fix crash in Date editor; getHost() is an unavailable function, now the same problem is handled via the new imagePath field in the editorOptions.
Date editor: parseISODate() is not availble and cannot find which library would provide this API -- temporarily discard it until we really fix this, just no crashes for now please
Slick.Event.unsubscribe() now accepts an empty arg, which will cause it to unsubscribe ALL registered handlers -- handy for the unit tests, for one.

Slick.Event.subscribe() now returns the registered function so you can write things like this:

    var registered_handler = grid.onResize(function() { blurb; });
    ...
    grid.onResize.unsubscribe(registered_handler);
- unit tests: fixed (also point to the new jQuery and event.drag library files)

- unit tests: added one more to test event trigger order on grid resize.
- added an image to show the sort column in 'undetermined / unsorted' state so that it is visually recognizable as sortable (current CSS style did not show this)

- regenerated the sort images from Photoshop template (template included): using PNGs but using the blue color of the (old) GIFs
