IE8 Fixes (part 2)

Three small fixes here:

* #434 - CSS tweaks: Adding fallback colors for `rgba`, and swapping `::after` for `:after`
* #435 - Enable CORS support in jQuery
* #430 - Click event handler changes
Sorry, I mean, with this change, it's properly talking to the API and all the CRUD is doing what it's supposed to.  At least so far as I can tell.
