Updated git submodules

Project: appc master 50472bf49f725bf6c4ea659ca7e387a2c6436ff2

Fixes feature install on latest ccsdk

Updated rest adapter to resolve dependencies the same way that other
appc features do. This fixed the karaf crash during install.

Added necessary dependencies as embedded or karaf bundles to other
appc features, as needed.
