* MODDED VERSION TO WORK WITH CASH JS, SEARCH "// MOD" for changes | |
* main changes: | |
* - changed draggable!=false selectors to draggable=true | |
* - mapped event to event.originalEvent in swipe functions since cash does not do this | |
* - removed es5 module stuff with auto jquery insert and replaced it with addSlick export function | |
* - added missing basic jquery methods in shim.js to cash before adding slick via addSlick | |
* ($.type, $.proxy and $fn.end e.g.) | |
