Droplet update

* merged private droplet fix: https://github.com/dabbler0/droplet/pull/27
* moved droplet/ace init code to the afterInject() function. previously, we were relying on droplet and ace loading quickly, but it was timing sensitive. since we already call afterInject() only after the requirejs load of droplet is complete, it makes much more sense to move that init code into that method.
