Epic to group issues regarding travis builds for all our ios libs and demos

Travis builds started to fail recently. Currently there is a transition process to XCode 5 and possible there were some configuration changes in the travis environment that need to be reflected in our configuration scripts.

The epic will track the progress on updating our script for both the libraries and our demos.

Further every project must include a build success/failure icon on the README.md (in places it is missing)
