Subject: [PATCH] Use native bridge for animations

Basically patches in the change from https://github.com/facebook/react-native/pull/10289/files.

Once the above commit is merged into RN and pushed to a stable release, this can be merged. It won't be backwards compatible with older versions of RN, however.
