- [IOS-1841] Fix for flashing that occurs when canceling hamburger top view swipe transition when a custom zoom transition also exists.

I had to fork the ECSlidingViewController repo as part of this change.  I had to also add this new forked pod spec file to the OpenTable Specs repo or else I couldn't get the project to build due to the dependency that OTCommon has on this pod.

Still need to setup a Jenkins build track for this library once approved.
